<pre>Make sure your kernel has this patch:
<a href="http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=227ae10f17a5f2fd1307b7e582b603ef7bbb7e97">http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=227ae10f17a5f2fd1307b7e582b603ef7bbb7e97</a>
You can also try disabling tiling in your xorg config:
Section "Device"
Identifier "Radeon"
Driver "radeon"
Option "ColorTiling" "true"
Option "ColorTiling2D" "true"
EndSection</pre>
