Comment # 91 on bug 78453 from
Thanks Kai, for your answers. I got it working now as well - in fact I'm typing
from an accelerated xorg that's running for over an hour now.

I used:
- agd5f's kernel (drm-next-3.17-wip), including the "handle ASIC_ProfilingInfo
v3.1" patch
- ucode from comment #81 copied to "/lib/firmware/updates/$(uname -r)/radeon"
- xf86-video-ati with agd5f's patch from comment #81
- mesa git with glisse's patch from comment #86
- llvm git
- xorg-server 1.16
- glamor 0.6.0 (is that still necessary with xorg 1.16 ?)
- kernel command line parameters: radeon.dpm=0 drm.rnodes=1

I do not use any kind of login manager (gdm, kdm) for login, but plain old
text-mode, then typing startx.

Both xfce4 and cinnamon start up and work, but at least in cinnamon I get
massive flickering on mouse-overs or animated cursors (terminology). For
example the background image occupies the whole text-area where I type this
comment, whenever I move the mouse in or out (firefox). The same happens when I
type, but obly for 2-3 lines of the surrounding text.using the mouse-wheel to
scroll helps and corrects the display.

I am able to run glxgears. And I even tried World of Warcraft via wine, where I
could get to the character selection screen (3D character is displayed), but
upon entering the world, the machine crashed and I got the screen full of noise
as output (similar to what happened before the fix on crashes).
