I also have a bug that is similar to this one but with the 2.6.32 kernel 
series. I reproduce it at 100% percent with the last xorg git stack as 
well as the regular stack but in my case the gpu freezes when xorg is 
starting. however I have no problems with the 2.6.31.x kernel series and 
the same xorg stack. So the problem is coming most probably from the KMS 
stack.
