I have no objections to this.  In fact, in Fedora at least (I floated
the idea in #nouveau a while back too), in the near future I plan on
having the DDX fail to load on all GPUs where modesetting+glamor can
be used (unless overridden by a config option).

So, this seems like a good step towards that goal.
