Just some notes for the N810:

- Read battery voltage from /dev/retu with the kcbatt tool here:
http://mrrau.dyndns.org:23280/n800/kcbatt/

- Perhaps other things from this list could be read from /dev/retu the same 
way, but I don't see the time here unfortunately:

- Set up bme for battery charging (use at your own risk of course):
1. Copy initfs to /root/initfs or somewhere
2. Put the two attached files in there and 'chmod +x' them
3. Run, as root: 'chroot initfs /c_bat' (after each boot)
4. Test; you should be able to charge your battery now
