Same patch as before, but adds nv40 and nve0 as on by default, and removes end
user ability to turn it on for nv50/nva3/nvc0.
I finally found the nv50-related stuff you nuked, and yeah, the current code
definitely can't work as-is. Oh well. I'll play around with reinstating it in
one way or another.
