Could you please test glxgears and other simple mesa demos? It's easier 
to spot the problems with small apps that don't use a lot of complex 
shaders. If some of them don't work correctly, please send me the dumps 
with "R600_DUMP_SHADERS=2 R600_SB_DUMP=3". Also it might help if you can 
look for piglit regressions against the piglit results with R600_SB=0 
and send me the dumps for a few regressed tests.

Thanks for testing.
