Just because something is called "powersave" it doesn't mean something actually saves more power. ;-) As far as I followed the discussions most people these days believe that the default governor is best for all cases. (Doing something quickly on a fast CPU appears not to be worse when it comes to power consumption than doing it for a longer timer on a slow CPU... Not totally surprising, is it?) [1] Fiddling with userspace configuration of CPU governors is something for Gentoo --omg-optimized folks... http://funroll-loops.info/ For everything else on this topic I defer to Matthew, he obviously has more of a clue on this than I do.
