[Nouveau] [patch] add nv50 voodoo

[Alexey Dobriyan]

Hi, this is from mmio-traces. After startx I see mouse cursor which
moves, background split into black and garbage areas. First area
consists of repeated pattern of something. Surrealistic picture, and
after several seconds box locks up hard, monitor turns off.
However much improvement against non-starting X. :-)

Card is 10de:0191 (GeForce 8800 GTX)
