Comment 32 for bug 432598

I tested this with both devkit-power --dump and upower --dump, to check that both the old devkit-power-gobject as well as the new libupower-glib work.

The only gotcha with this approach is that the UpClient does not send out property change notifications if the PK privilege is changed, so enabling/disabling suspend/hibernate currently requires a session restart (in the case of long running clients like gnome-session).
