Default PowerMizer settings in not taking effect (Quadro FX 2700M, v256.35)

Hi all,

I have a Dell M6400 with a Quadro FX 2700M running openSUSE 11.2 and v256.35 of the NVIDIA drivers.

I want to reduce the performance level to save power and reduce heat.

Current settings:
nvidia-settings -q GPUPerfModes -t
perf=0, nvclock=169, memclock=100 ; perf=1, nvclock=275, memclock=300 ; perf=2, nvclock=400, memclock=300 ; perf=3, nvclock=530, memclock=799

nvidia-settings -q GPUCurrentPerfLevel -t
nvidia-settings -q GPUCurrentClockFreqs -t

I tried adding the following line in the "Device" section of my xorg.conf and rebooted but it had no effect:

Option "RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerDefault=0x1; PowerMizerDefaultAC=0x1"

That was with v195.x.x of the driver. I then installed v256.35 and reran nvidia-xconfig which produced the xorg.conf shown at the end. nvidia-xconf moved my lines to the "Screen" section but after a reboot, the performance levels were the same.

How can I get this to work?

Many thanks!
