The original bug with the screen corruption is definitely fixed (though
it doesn't look like there have been many DRM changes in -CURRENT
lately, so I'm not sure what actually fixed it). 

I did encounter another, separate problem (which I first thought was
related to the screen corruption), where *most* opengl applications
would just display a black window, but this was resolved by using Mesa
from git.  I know it's a separate bug as I saw this black window problem
on another machine that had always worked previously and never seen the
screen corruption.

I did not open up another pr for this new problem as I knew you were
going to be working on merging in Xorg 7.3 and I thought I'd wait to see
if was a problem afterwards.
