Just to tie up a loose end... I tested Andi Kleen's new patch for this
issue on 2.6.18.3. While the patch didn't automatically detect the VIA
chipset in my Asus A8V Deluxe, it allowed me to manually set a boot
option that fixes the problem (by disabling DMA to addresses over 4GB).
The fix is essentially the same as Andi posted here
http://groups.google.com/group/linux.kernel/msg/b1e820ef0212ee5e
although you have to patch pci-dma.c now, not pci-gart.c.
As another note - with my AGP aperture set to only 64MB, 3904MB are
visible. With the aperture set to 256MB, the full 4096MB are visible.
