not sure if this relates to you, but here's what i just went thru:
my energy saver settings kept reverting to reduced; tried everything.
permissions, diskwarrior, etc etc.
archive & install.
the "genius" bar.
finally, apple suggested i reinstall everything, even "zero'ing" the drive.
AFTER all of that, i have the problem again. turns out:
if you've changed "AM" and "PM" in the international pane for your menubar clock, it can interfere with your energy saver settings.
a repeatable bug for me, and some others.
have you changed your settings for the clock?
just a thought (and a good story, anyway)...
