I've applied the radeon patches tagged for -stable and tested that on
3.8.0, but that doesn't solve the resume problem.  Any ideas of anything
else I can do to test this?  Doing a "backwards" git-bisect is a pain,
but I guess I can do that to try to track down what patch fixed this, if
that's the only idea people have...
