Hi,
My 790gx chipset supplies an rs780. With .34+ all is ok. With .35-rc5 basic function seems ok (kde works) but
games like extreme tux racer have problems. The cursor does not display when on the tux racer window and
various objects flicker on and off as I attempt to play the game.
Here is what .34+ detects (think this kernel has a drm-radeon-testing from may or early june)

Did you update anything on the userspace side (ddx, mesa, xserver)?
Can you bisect what commit is causing the problems?

2.6.35 added support for vram greater then the size of the PCI
framebuffer BAR (256 MB in your case). The amount of vram accessible
to the CPU is limited by the size of the PCI framebuffer BAR, however
the GPU can access the entire amount. 2.6.35 works around this
restriction so that the CPU can access the entire amount of vram.

Sounds like it might be
https://bugs.freedesktop.org/show_bug.cgi?id=28341 . Does the X driver
patch attached there fix the problem?

Michel,
xf86-video-ati git from today fails. Applying the revert patch in the above message
fixes the problem. Its an interesting bug in that the kernel change triggers the
driver bug. Might be a good idea to get this fixed, one way or another, before
-35 gets released?
Let me know if you want me to test anything.
Thanks,
Ed Tomlinson

It's basically a userspace bug, the buggy userspace code is just only
active with new functionality in the new kernel.
