This looks like the event devices are not available when pbbuttonsd
is started. With version 0.7.0 pbbuttonsd rely full on /dev/input/event
%. If you compiled pbbuttonsd with --enable-debug it would show all
found input devices at startup.
Another posibility might be the lack of interrupts on AC power. On my
Pismo for example the AC connector is only recognized by the kernel if
the PMU sends interrupts. If I booted by machine without a battery
plugged in, this interrupts never come and so the kernel doesn't know
that it is running on AC power. /proc/pmu showed that the machine is
running on battery without a battery mounted (not very funny). Maybe
you have to look in this direction?
