Yeah, makes sense. I also found the vboxvideo driver in staging which
needed an API tweak.

I've pushed that as drm-lease-v5 and will plan on dumping that to the
list when you're done with -v4.

There are a couple of conflicts and another update needed when merging
leases and the new vblank ioctls together; once we've got one of the two
ready to go, I can rebase the other on top of that and fix things up.
