To put my $0.02 in, I seem to recalll there being a UPS addon for linux. 
Could we do something similar? From what I remember, all it did was 
monitor the serial connection to the UPS (APS brand I think) and if it 
got a signal that there was a problem, it would do somethign like a 
shutdown -h now. This doesn't seem too hard. Maybe even a LKM?
