Hi Paul:

Power Management can mean many things, just what kind of power
(electrical tracking) support do you need??  Whenever I've heard that
phrase I've always thought it referred to Linux or Unix being in sync
with a UPS (Uninterruptible Power Supply) so that at brown outs or
power surges the system has time to receive signals from the UPS
regarding what is going on, the battery condition of the UPS and when
the system needs to shutdown, etc.

Maybe that kind of power management is overkill for you; maybe you just
want a simple power indicator which is available within e17.  However,
before I assume anything further it would help if you explained a bit
more.
