Ok, then it is more than sane to add all power management related methods
here. Like all display brightness related methods which are already in
Hal. Well if we mirror DPMS settings because on some systems we don't have
an X server, then we have to mirror _all_ power management related tasks,
because there are also systems which have no running hal. Like UPSs,
battery information, ac states.  We would have to duplicate almost
anything on org.freedesktop.PowerManager.
