So I started something, it is at.

https://github.com/pavelmachek/libbattery

My battery on n900 is currently uncalibrated (and charging), still it
gets some kind of estimation:

Battery -1 %
Seconds -1
State 1
Voltage 3.88 V
Battery 63 %

Of course, there's a lot more work to be done.

Best regards,
