Hello. I am happy to report that v3 of Jerome's patch works and fixes
the regressions. I have tested 3.4 with the patch against Ubuntu's
stock drm, radeon and mesa-glx packages.

A quick reminder that the patch needs the small fix detailed in my
exchange with David above.

Thanks very much to Jerome and David!
