Radeon/Irongate patch

[Aaron Lehmann <aaronl@vitelus.com>]

This hack makes the Radeon work on an AMD761 chipset. I've tested it
personally. It should suffice until CVS' real fixes eventually get
merged in.

For users of DRM, SCT's similar kernel patch at
http://uwsg.iu.edu/hypermail/linux/kernel/0109.1/0752.html may be
important.
