Except, apparently, me:
[bilbo@beta bilbo]$ cat /proc/driver/nvidia/agp/host-bridge
Host Bridge: Via Apollo Pro KT266
Fast Writes: Supported
AGP Rates: 4x 2x 1x
[bilbo@beta bilbo]$ cat /proc/driver/nvidia/agp/status
AGP Rate: 4x
Fast Writes: Enabled
This is a KT333, like I've said before. I'm using agpgart, though (kernel 2.4.19, again).
AFAICT, the KT333 is just a KT266 that supports faster DDR memory (DDR333, PC2700, instead of DDR266, PC2100), which is why the PCI IDs are all the same, and the kernel detects it as a KT266. But I'm not positive on that, I haven't seen schematics.
