I'm going to have to remove some local patches from my tree and try to
get this fixed.  The patch that I posted apparently doesn't resolve the
inconsistent mapping.  I hadn't realized that the patch that warns about
this had made it into the tree.  Anyway, I'm glad that this gets things
working at least.  I still need to test with some other cards, but so
far, I think the following have been tested.

r6/700 amd64 pci-e
r600 i386 pci-e
r200 i386 pci (This should be the same code paths for r300 as well)
mga amd64 agp

It still needs to be checked on intel and nouveau, at least.
