Call for testing: GNOME/KDE related power consumption tweaks

[Mark Kretschmann]

My last tests with KDE trunk and PowerTOP (maybe one month ago, right
after the Phonon fixes) showed that Amarok generated almost no wakeups
when idle. When not idle the number of wakeups wasn't critical either.
Things looked surprisingly well in this regard.

So I currently don't see any reason to worry.
