thank you. I tried to cherry pick this patch on top of Linux tip, but
was not able to:

Probably I'm missing a dependency.

Than I checked out drm-nouveau-next of
git://anongit.freedesktop.org/nouveau/linux-2.6 and tried again. This time it
worked. Thank you. Will the fix wander to upstream before v3.13?
Otherwise I would appreciate a heads-up when it wanders upstream, so
that I can test again.
