While nvfx (3d gallium driver) isn't supported, i run few tests with
nouveau-git (commit 72690683e35680d912e9b8ff2ee0b7a18631dd0d - "drm/nouveau/pm:
Document and expose CL and WR for 0x1002Cx") and mesa-7.12-devel (OpenGL
version string: 2.1 Mesa 7.12-devel (git-a09b7f7)).

Other software - Q3 Arena linux demo.

Results kinda strange.

Default settings
Timedemo 1 
demo demo002 - lock up card very fast, can power off machine via ACPI.
demo demo001 - works!

geometry detail set to low
demo demo001 - not tested
demo demo002 - works!

geometry detail set to medium
demo demo002 - lock up after some time (not at start of level)

For perflvl=0 

even demo001 lock up after some time in the middle (always at same place).

So, I guess we run ahead or behind GPU, mostly in sending geometry data? need
more test with perf mesa demos, for example ....

currently my performance levels are

drm] nouveau 0000:01:00.0: mem timing table length unknown: 14
[drm] nouveau 0000:01:00.0: 2 available performance level(s)
[drm] nouveau 0000:01:00.0: 0: core 300MHz memory 1000MHz voltage 1300mV
fanspeed 100%
[drm] nouveau 0000:01:00.0: 1: core 500MHz memory 1000MHz voltage 1400mV
fanspeed 100%
[drm] nouveau 0000:01:00.0: c: core 100MHz memory 501MHz voltage 1300mV
[TTM] Zone  kernel: Available graphics memory: 255992 kiB.


and perflvl 1 lock up whole machine pretty fast (before i managed to run any
bench, even  with just composited, via Xrender/Kde 3.5.10 desktop)

Guess I need additional "bug" for tracking this. And probably one more for
tracking invisible VTs after s3 sleep ....
