I decided to do one final test an found it works with just setting "ColorTiling" "off" in xorg.conf and all patches in both userspace and kernelspace intact.
colortiling is off by default and is automatically disabled if your kernel is not new enough. Lets try and clarify what the problem is. Try the following configurations (start each one from with a cold boot):
1. drm-radeon-testing + the patch from bug 28327. No patches to ddx or mesa. No tiling options in your config
2. drm-radeon-testing + the patch from bug 28327. ddx and mesa patch with tiling patches. no tiling options in your config.
And report back what happens.
