If it makes you feel any better, I couldn't get sample mask to work on
nv50/nvc0 either. I'm sure the issues are unrelated. However one thing
I noticed when I was investigating was that the SAMPLEMASK output was
being listed ahead of the COLOR output, and the nouveau codegen logic
wasn't really ready for that... I guess COLOR had always come first
before. Of course fixing that didn't fix the samplemask issue, but
thought I'd mention it.
