I just experienced some slightly strange behaviour on my h3900, which
might be related to this. The ipaq was sitting quietly on my desk,
suspended, and had been that way for a couple of hours. All of a sudden
it woke up for no apparent reason, and sat there for a few minutes until
ipaq-sleep suspended it again.

If this is happening often, it would obviously cause abnormally high
battery drain. Perhaps we should add some extra instrumentation to the
wakeup handling code in h3600_asic_battery.c to find out what the cause
of these mysterious awakenings might be.
