Which patches are you referring to?

> 2. diff origin...dave_drm/drm-radeon-next

> kms work fine
Does an updated tree without the patches also work?

Created an attachment (id=26191)
--> (https://bugzilla.kernel.org/attachment.cgi?id=26191)
output from patch -p1 for all three patches
I tested kernel-2.6.34-rc6 from git. The kernel itself has not fixed the hang.
The patches probably do not apply, because the patched files have changed too
much. I attached the output of 'patch'. However it would be great, if you could
adjust them.
The "add accel parameter patch" applies mostly correct, so the radeon.accel=0
works and in consequence the brightness changing (as Alexey said).
But so far I could not get kms completely to work.
