Are you using the Novell radeonhd driver? (I think SuSE default to this for all
cards > r500).

This isn't the driver that is developed by the opensource community and
really your distro is where you complain about that sort of regression.

The wierd thing is we see distro picking up fixes for userspace
drivers *much* quicker
if their teams are the on the ball since they are only a small
component to upgrade,
with the kernel you find most distro fire and forget, so if 2.6.31
doesn't work on your
hw you'll wait 6 months to find out that 2.634 doesn't work either.

Since ppl aren't targetting stable properly distros are left to fend
for themselves
when it comes to backporting large amounts of changes, and you find most
distros just don't bother.
