I'm using the Mythcenter theme which seems really fast.

I have both settings that I've read are needed to reduce the shared 
memory to 64MB...

In my xorg.conf Device section:
     Option         "RegistryDwords" "RMDisableRenderToSystem=1"

And for the nvidia module, I pass the following options:
options nvidia NVreg_RegistryDwords="PerfLevelSrc=0x2222" NVreg_Mobile=0

However, I still get:
(II) NVIDIA(0): NVIDIA GPU GeForce Go 7300 (G72) at PCI:1:0:0 (GPU-0)
(--) NVIDIA(0): Memory: 131072 kBytes
(--) NVIDIA(0): VideoBIOS: 05.72.22.68.00

The underclocking script does seem to be working with a confirmation by 
nvidia-settings.

Any clue why this doesn't work for me?  I'm running driver 177.
