It may be that nVidia cannot provide an adjustable Powermizer feature because:
An OEM has explicitly requested Powermizer *not* be configurable.
Powermizer is controlled by the small microcode that is loaded upon driver initilization and cannot be altered unless an X restart is performed. This would explain as to why it is an xorg.conf setting and not a nvidia-settings setting.
