This might be a bit off-topic, but I have tried to get the battery on
the Nokia N900 working, and so far I'm only able to query the
remaining capacity, but not really to enabling charging. This is very
annoying, as I can only hack a certain amount of time, and then I have
to reflash, reboot, and wait for the batter to charge with the
official system (if there's enough power to flash).

Do you have any hints how to do that?
