Maybe it isn't the only driver? This commit broke video on my system with a G86 [Quadro NVS 290]. Bisected to d02117f8efaa5fbc37437df1ae955a147a2a424a, and reverting it restored functionality.

drm/nouveau: init the base GEM fields for internal BOs
TTMs buffer objects are based on GEM objects for quite a while and rely on initializing those fields before initializing the TTM BO.
Nouveau now doesn't init the GEM object for internally allocated BOs, so make sure that we at least initialize some necessary fields.
Regards, Christian.

Maybe it isn't the only driver? This commit broke video on my system with a G86 [Quadro NVS 290]. Bisected to d02117f8efaa5fbc37437df1ae955a147a2a424a, and reverting it restored functionality.
