I got bored, and started messing with the code. Found a
apply_dcb_connector_quirks function on nouveau_bios.c, made by Ben
Skeggs to fix a similar problem I had with a different card, and seems
pretty easy to extend it for this new card. But my C skills are very
rusty and it feels "too easy" to be true, so now it scares me to build
and run my own patch.

Can somebody have a look at it and hit me in the head if I'm doing it wrong?
