Hm, but why do both Windows and OSX work out of the box here then? (yes,
not a very qualified statement)

Ah, ok.

IMHO, the whole power management stuff (including the battery plugin)
should be done in a sane and well-integrated way, w/o any unnecessary
action on the users side. I'm not sure, but maybe GNOME's power manager
is worth a look? Dunno how messed up it is, but maybe we can convince
them to clean it up, so we can use it in Xfce as well? That'd probably
reduce the additional overhead.
