Comment # 5 on bug 31122 from 
What do the Fn+X keys do? I assume they just act as a keypress? (And I'm
guessing that the nv driver hooks into that somehow... although the only
reference to 10f0 that I see is in turning the thing on/off, perhaps it just
leaves something untouched that nouveau touches and messes up.)

This should be fairly easy to implement... You know what register to control,
what the min/max are. I'm guessing it's just 10f0 that matters -- the other
register controls whether the CRTC is on/off.

It should be easy to stick something into nouveau_backlight.c that deals with
your sitation. Instead of keying off of card family, you'd key off of
dev->pci_device, like dfp.c:nv04_dfp_update_backlight does. You should give it
a shot if you're interested.
