The wasted space seems of limited importance.

More important is to check which distros have the new powertop.

F16 and F17 seem to have powertop-1.98, which I assume is the new
world order already. But maybe I assume incorrectly.

F14 (which I personally still use, since it doesn't have gnome3) is 1.13.

SuSE, Ubuntu?
