[drm] fix radeon aperture issue

Browse source 
Ben noticed that on certain cards we've landed the AGP space on top of
the second aperture instead of after it..  Which messes things up a lot
on those machines.

This just moves the gart further out, a more correct fix is in the works
from Ben for after 2.6.15.
