Just some food for thought:
If you split it into a enable/disable (0/1) attribute, and a level
attribute

on/off doesn't really make sense if the question is "do you favor power
or do you favor performance".......

How about just making it a numeric scale with 0 meaning no power saving
and then some fixed number of levels (e.g 0-9)?

The original proposal seems far more intuitive than these alternatives.
