I added a 20-radeon.conf to xorg.conf.d with this content:
ephraim at errorl:~$ cat /usr/share/X11/xorg.conf.d/20-radeon.conf
Section "Device"
         Identifier  "TheCard"
         Driver "radeon"
	Option "ColorTiling2D" "False"

And found this in Xorg.0.log:
[  2219.770] (**) RADEON(G0): Option "ColorTiling2D" "False"
[  2219.771] (II) RADEON(G0): KMS Color Tiling: enabled
[  2219.771] (II) RADEON(G0): KMS Color Tiling 2D: disabled

But it changed nothing regarding 3D glitches.

Should I downgrade to ver. 8.0.5?? I though that xf86-video-ati needs 
mesa 9.X.X ??
