Abbreviations:

K7 - AMD Athlon (and Athlon XP and Socket-A Semprons)
P7 - Itanium (Merced)
Xeon - Larger cache versions of the Pentium II, Pentium III, or Pentium 4
SDRAM - Synchronous DRAM (unbuffered)
Reg SDRAM - Registered SDRAM DIMM
DDR PC2100 - PC2100 Double Data Rate SDRAM (unbuffered)
Reg DDR - Registered Double Data Rate SDRAM
RDR PC800 - PC800 Direct Rambus DRAM
RDR 4i - 4-bank Direct Rambus DRAM
RDR 32 - 32-bit Direct Rambus RIMM module (two 16-bit channels on a single RIMM module)
HSDRAM - High speed SDRAM (lower latency and lower tAC PC133 SDRAM that runs up to ~150MHz). This isn't a different memory technology; it's souped-up PC133 SDRAM.
Mem=3/4 Bus - Can run the RAM at 3/4 the speed of the System Bus
Mem=AGP - Can run the RAM at the speed of the AGP bus
DC - Dual Channel
QC - Quad Channel
FB - Fully Buffered DIMM
PCI 2.2 - Complies with PCI spec rev. 2.2.
PCI 66/64 - Supports a 66MHz or 64-bit or both PCI bus (which varies from chipset to chipset). Chipsets often implement this feature with add-on modules, not as a standard feature.
Unless otherwise noted, assume PCI 2.1 compliance.
AGP - Accelerated Graphics Port
- 0.8v and/or 1.5v - AGP buffers only operate at 0.8v or 1.5v levels; they are NOT 3.3v safe. This excludes some older AGP cards (like the 3dfx Voodoo series, Matrox G200, and Intel i740-based cards) from use in motherboards with this chipset. Quick rule of thumb: if your card supports AGP 4x mode, it should fit and operate in a 1.5v AGP slot.
SMA - Shared Memory Architecture (a bit different from UMA; basically an integrated AGP implementation)
UMA - Unified Memory Architecture (shared memory)

Notes:

The ECC/Parity column refers to whether or not the chipset supports error detection and correction for the system RAM. It doesn't indicate whether any onboard L2 has error detection. Also, any ECC function for the L2 cache on various sixth generation chips is handled exclusively by the CPU itself; the chipset doesn't deal with this. A 'Yes' in this column indicates there is some sort of error detection, but I'm not sure what flavor.
Many chipset features (such as the maximum amount of L2 cache or pseudo-synchronous operation) are not always implemented in all motherboards. Simply because a chipset supports a particular feature doesn't mean your motherboard necessarily has that feature.
The only bus speeds listed with each chipset are those that it officially supports. The Athlon, Willamette, Foster, and Merced chipsets all use a dual (2x) or quad-pumped (4x) bus that hits on the rising and falling edges of the clock, yielding a faster effective bus speed.
Running chipsets at odd bus speeds (75, 83, 112, 124MHz) can be hazardous to your system's overall stability. Most chipsets can only run PCI/AGP components as well as IDE channels synchronously, which forces the various buses to run outside their specifications when running at 75/83/112/124MHz. You won't physically damage the components by running them like this, but it can cause a system to behave erratically or even corrupt the occasional hard drive partition. Use with caution.
ALi changed its name to ULi.
The ALi/ULi M1695 can accomodate AGP 8x cards, but will only run them in PCI mode.
nVidia bought ALi.
The ATI IXP250 adds wake-on-LAN and DMI functionality over the IXP200.
The ATI Radeon CrossFire Xpress 1600 used to be named the Radeon Xpress 200 CrossFire.
The ATI Radeon CrossFire Xpress 3200 can use the M1575 or SB600 southbridges.
AMD bought ATI.
The ATI Radeon CrossFire Xpress 1600 and 3200 were changed to AMD 480X and 580X, respectively, after AMD acquired ATI.
The AMD 980a chipset is a rebadged 780a.
In October, 2002, official PC1066 RDRAM support was added to the 850E chipset.
The Intel 855 (Tulloch) chipset was originally billed in the press as being simply a cut-down version of the 850 Tehama, with a single Rambus channel and smaller memory capacity for use in lower-end systems. Later "reports" pegged it as a Tehama successor supporting 4i Rambus, 32-bit RIMMS, PC1066 RDR, and even 8x AGP. I'm honestly not sure which leaked specs are correct. And since it was cancelled, we may never really know.
The Intel 845G and 845GL are picky in what memory specs they support (single-sided/double-sided, etc.) See Intel's datasheets for more info.
The Intel 845GL and 845GV do not support an AGP slot.
The Intel 7205 chipset can only run its memory synchronously with the FSB. Identical pairs must be used for Dual Channel operation.
The Intel 945GZ chipset does not support any PCI Express slots.
The PCI bus is no longer supported starting with the 7-series of Intel chipsets.
The nForce3 Pro 150 has a 16-bit downlink and 8-bit uplink for its Hypertransport link. The nForce3 Pro 250 has 16-bit links for both directions.
The various nForce 5xx chipsets vary mostly by PCI Express lanes.
The SiS 645 and 650 chipsets support up to 3GB of PC2100 DDR SDRAM. When using the faster PC2700 (DDR 333) only 2 DIMMs can be used, limiting the chipset to 2GB max mem.
The SiS 646 chipset was renamed 645DX.
The SiS 648FX chipset supports up to three DDR-333 (PC2700) or two DDR-400 (PC3200) DIMMs.
The SiS 650GX is the same as the 650 chipset except it does not support an AGP slot.
The SiS 651 chipset can support a maximum of three PC2100 DDR DIMMs or two PC2700 DDR DIMMs.
The SiS 661FX chipset can support up to 3GB of PC2700 DDR or 2GB of PC3200 DDR.
The SiS 655TX adds "Advanced Hyperstreaming Engine" over the 655FX, otherwise they're the same.
The SiS 741 chipset supports an external AGP slot in addition to its internal video chipset. The SiS 740 chipset does not have the external slot.
The SiS 760GX may also be paired with the AGP-supporting 964 southbridge.
I'm not exactly sure what the differences between the VIA P4X-266A and P4X-266E are.
The VIA PT-600 and PT-800 were originally named the P4X-600 and P4X-800.
The VIA KX-133 does not support the Thunderbird or later Athlons because of different bus signal types.
The VIA KZ-133 chipset was renamed to KT-133.
The VIA KT-133E chipset supports the PowerNow! Features of the mobile Athlon/Duron CPUs, though it can still be found in desktop systems.
The VIA KM-133 chipset allows an AGP slot in addition to the integrated graphics; the KL-133 does not have the AGP slot.
The VIA KT-266A comes with memory performance enhancements over that of the KT-266.
The VIA KT-333 may be paired with the VT8233 or (on some boards) the VT8235.
The VIA KT-400A may be paired with the VT8235 or the VT8237.
The VIA Apollo Pro-266T, P4X-266, and P4X-266A all may come with the optional PCI-66/64 VPX controller.
While many Athlon-compatible VIA chipsets may claim support for ECC memory, they may not actually utilize the ECC functionality beyond the booting stage.
The VIA K8T-400M used to be known as the K8HTB.

"PC150" and "PC2400" are not recognized specifications; they're just overclocked PC133 SDRAM and PC2100 DDR.

QDR SDRAM is not a different type of memory. It is standard DDR SDRAM that is utilized by the chipset as a double-sided memory stick where each DIMM bank (side) can be accessed almost simultaneously. This obviously will only work with double-sided DIMMs and requires a specially designed DIMM to deal with the signalling.

When used with a 133MHz FSB (front side bus) PC600 Rambus only operates at 266MHz base clock. When used with a 100MHz FSB PC700 only runs at 300MHz base clock. PC800 can operate at 400MHz regardless of the speed (100 or 133MHz) of the FSB. PC700 is only supported on the i820 chipset.

Rambus 32-bit RIMMs are effectively 32-bits wide, but in reality two 16-bit wide channels are contained on one module, so the chipset still sees it as dual channel. The same is true for 64-bit modules; they use four 16-bit channels on a single module.
