SubjectRe: [RFC/patch] macro_removal_agp_mtrr.diff

Okay here is an updated patch:

I've taken suggestions from Christoph and Arjan on board,

My only issue is with the stuff in drm_os_linux.h, I've had to make a
dummy AGP structure, and add the mtrr_add/mtrr_del stubs (as they are fine
on x86 but don't exist on anything else..) but perhaps a small ugly in
there is better than big uglies elsewhere...

I might be able to drop the OS_HAS_AGP from the drivers, but that'll be a
job that requires testing via CVS (as that is where we have the people
with the different cards..)

Dave.
