This isn't universally true: I run the proprietary nVidia driver with
a GeForce FX 5600 on a Tyan Thunder K8W dual Opteron, and the main
problem I have is not with the AGP card, it's with the second (PCI
GeForce FX 5200) display, on which I get absolutely lousy (PIO-like)
performance.

But I *have* to use the kernel AGPGART implementation of the AMD-8151
bridge instead of the nVidia driver's AGP subsystem: if I try to use
the driver's, I get a hard lock.

Cheers,
