I complained few days ago that 'agpgart.o' module from 2.2.18pre
is causing a kernel oops. The problem turned out to be an apparent
assumption that PCI memory <-> memory mapping is an identity and
this is not always the case.
Here is a patch applicable to all 2.2.18pre kernels with agpgart

On UP1100 Alpha with an AGP slot and "Advanced Micro Devices [AMD]
AMD-751 [Irongate] System Controller" an attempt to use 'agpgart'
support ends up with an oops. I tried 2.2.17 and 2.2.18pre15 kernels.
With CONFIG_AGP=y and CONFIG_AGP_AMD=y resulting kernel gets stuck
after oops and does not
