Okay, The patch I just posted might fix this bug. It doesn't cause any additional errors in piglit either. I think its working right with http://github.com/jckarter/hello-gl-ch3 too. Of course I have only tested it on my RadeonHD 3100 and its my first attempt at r600 assembly so let me know if it works for you.

Note: it could probably be done so its faster but I'm still not to sure on how everything works yet in the software
