If we were to allow this kind of "sharing" for all PCI devices would
that work out instead? Or would this layer still be needed?
Initially this layer wouldn't be needed, but I'd like to add some
awareness to the drivers, so the drm can tell the fb to stop doing
stuff and vice-versa if necessary.... but perhaps that could be done
with a generic layer also.. or via the lowlevel driver I have...
