	There was a UPS daemon posted to alt.sources recently.
Apparently the way these guys work is that they plug into your
serial port too.  When external power goes off, it just asserts
one of the lines in the serial connection (DTR?, I forget), so
all you have to do is watch for that line to come up and then
start your shutdown procedure.
