Try applying http://0x04.net/~mwk/gen.diff

This is known issue... the card is using only 1/8 of its execution resources
because of misextracted initialization values on G86. It'll be fixed for good
when the ctxprog/ctxvals generator [above] is finished for all cards.

If the generator doesn't work for you, add the following lines to
src/nv50_accel.c in DDX after "OUT_RING  (chan, NV50TCL_COND_MODE_ALWAYS);":

BEGIN_RING(chan, tesla, NV50TCL_WARP_HALVES, 1);
OUT_RING(chan, 2);
BEGIN_RING(chan, tesla, 0x1400, 1);
OUT_RING(chan, 0xf);

Either way, please report which of these work for you.
