    Fixes xvmc-softpipe MC entrypoint, amongst others.

causes R600 XVMC to render incorrectly, colours are wrong and there are extra artifacts.

Current git is OK with above reverted.

The original bug is actually in softpipe of all places. HW drivers seem to agree with what was going on originally.
Comment 2 Andy Furniss 2011-07-23 02:22:51 UTC 
I see this is reverted in master now.
