Well, you could just try to do the change, and then if you get EPERM, 
emit an error message
like "Unable to edit /etc/power.conf: Permission Denied", or something 
like that.

I'm still having a difficult time stomaching that PowerTOP is editing 
power.conf, running other commands, etc...and it's probably not 
PowerTOP's fault, we just don't have a good programmatic interface to do 
this sort of thing yet. But an alternate way to go might be to bring up 
a screen that gives you a detailed, step by step procedure, for 
implementing the suggestion.
