this seems to be a common misconception about maemo5 + battery monitoring.

the BME in mamemo only controlls charging from what i can tell, its basicly a software control for what the n900s internal hardware battery charger can do (ref: http://wiki.maemo.org/N900_Software_BME - read the part about stopping BME) the charging system will work fine without any intervention from the userspace hardware, because that battery charger chip allows basic safe charging, (and also allows charging from totally dead battery without the os needing to boot)

and release will be when i have some form of network connectivity be it gsm or wifi
