After a bit of poking around, it appears that the profiled is reading the data in /etc/profiled, but the UI aspect around the power button is missing.

I copied /etc/profiled/90.nokia.ini to /etc/profile/91.alan.ini, made an obvious edit, and rebooted. After this, the get_profiles call then listed my "quiet" profile in addition to the standard "General" and "Silent". It seems that a bit of GUI hacking may turn this into appropriate configuration.

Anyone have any idea why Tweakr didn't store the new profiles that you create with it in /etc/profiled? It seems the place...
