Heh, you are suggesting that KMS support has no merit? ;)

Right, but I thought we want to move on to support KMS.
If there is another big picture to glean such leftover devices, I'd
love to follow that.  But this patch itself is simple enough and it
can't regress the other existing mgag200 devices, so it's still worth
to consider, IMO.
