Afaics, no such work has been done yet within hal, which allows to
disable the different components.
On the other hand, gnome-power-manager already uses DeviceKit-power.
Will future versions of e.g. gnome-power-manager or gnome-mount fall
back safely on HAL or will there be no problem if DeviceKit-power and
HAL (with power mangement enabled) are run in parallel?

When approximately (weeks, months) do you expect this to happen?
I'm asking, because I wonder if it makes sense to package DeviceKit
(for Debian) in the meantime or if this will just be wasted effort.


Why is it that all of the instruments seeking intelligent life in the
universe are pointed away from Earth?
