The 2.6.33 drm will likely either be backported outright or be available
via l-b-m.  So that part of the need should be taken care of one way or
the other.

As to the ddx side of things, I'm kind of liking the idea of sticking
with 2.9.1, to preserve the ability for users to fall back to UMS if
they need to for some reason.  However, getting this bug fixed would be
nice too.

In looking through the git tree for -intel, there are 7 Xv patches from
Daniel Vetter on Jan 7th.  I assume one (or more) of these are needed?
If we can find out, I'd be willing to look at backporting them so 2.9.1.
