Exactly, thats why anything modesetting-related must be disabled for
renderD#.  Looking at the virtio-gpu device-specific ioctls I don't
think there is anything doing modesetting (which we would have to leave
out), so we can apply DRM_RENDER_ALLOW everythere I think.  Or maybe
there is a global switch to flip DRM_RENDER_ALLOW for the whole list ...

cheers,
  Gerd
