Actually I think this could be useful.

I sometimes (not 100% reproducable) have a problem whereby when I perform a reboot, my lpm is off (even though the Settings UI says it is on!) I have (possibly erronously) put this down to some sort of bug/timing issue/race condition with profilmatic, as i have a rule in their that turns on/off my lpm based on certain conditions.

This could be a quick fix.

EDIT: I guess from reading the script it will depend upon whether the my lpm state is correctly mirroring the gconf key or not (I suspect that actually the Settings UI is what is mirroring the gconf key)
