Odd behaviour with agpgart

2000-11-18 Thread John Cavan
I don't know if this is specifically a problem with the AGP driver or with X, but basically the AGP driver detects an aperture base address different from that of the prefetchable memory area of the video card and the mtrr's are not in agreement. I'm using this with a Dual P3-500mhz and a Matrox
