As of 5ff22ab I no longer experience any problems with color tiling on 6850 (so far at least).
I've just pulled mesa+ddx git again. Nothing changed.
To make it clear, I am using
http://cgit.freedesktop.org/mesa/mesa/ http://cgit.freedesktop.org/xorg/driver/xf86-video-ati/ http://cgit.freedesktop.org/mesa/drm/
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=summary
are you using any other drm stuff perhaps?
No, I'm using latest git versions, 64bit Gentoo, 2.6.39 (git) + some stuff from airlied repo (radeon-testing/fixes; I'm waiting for some 'stable' rc to test 3.0), Xfce4/xffw4 with composition enabled but I should note that I'm stick to r600g, I didn't tried r600c in months.
It's just a guess but perhaps your system is overwriting some files or you are using 32bit version of mesa (things like flash for example - I'm using chroot environment to create 32bit packages) ?
