VBIOS
with stock nouveau from kernel 3.19.0-1.fc22.x86_64
this nva8 came with a thinkpad t410
my pstate file looks like this:
03: core 135 MHz shader 270 MHz memory 135 MHz
07: core 405 MHz shader 810 MHz memory 405 MHz
0f: core 606 MHz shader 1468 MHz memory 790 MHz
AC: core 405 MHz shader 810 MHz memory 405 MHz
when clocking to 07 or 0f everything works.
however, when clocking to pstate=03 i get constant flickering (maybe <5-10 hz),
although the clocks do change, and nothing crashes. (i can change clocks back
to 07 or 0f with no more flickering)

(no second monitor attached):
