Default Re: Should there be an option to disable Powermizer?

On a notebook, I prefer to disable powermizer (i.e. full performance) on AC and enable powermizer (i.e. adaptive clock) on battery.

To do this, I added the following line to /etc/modprobe.d/options:

options nvidia NVreg_RegistryDwords="PerfLevelSrc=0x3322"

Different values for PerfLevelSrc provide different behavior:
02222 = disable powermizer on AC and battery
02233 = enable powermizer on AC, disable powermizer on battery
03322 = disable powermizer on AC, enable powermizer on battery (my setting)
03333 = enable powermizer on AC and battery


I haven't yet figured out how to specify the power mode to use when powermizer is disabled (e.g. say I wanted to disable powermizer always, but use full power on AC, and lowest power on battery). Any ideas?
