Hi Chris,

I looked over your patches this morning and at first glance, they look 
good!   Unfortunately, I ran the piglit tests and got failures.  Not 
entirely sure what's going on there.  Endianness issues perhaps?

I'll try and take a more detailed look later this week.

Thanks so much for doing this!
