Please try running pmud with the -s or -S flag (signal init on power low)
and take note of the battery power level readings. I suspect the kernel
does return erroneous power readings on occasion, causing pmud to trigger
sleep. I've not been able to reproduce this on my Lombard Powerbook -
other users (iBook IIRC) report the battery power suddenly dropping to
zero from as much as 80%. I'm currently trying to collect more information
on this new feature.
