Looks nice to me. It even knows about dependency between temperature
and remaining power :-).

Hi!
This is driver for batteries with ds2760 chip inside. Such batteries
used in almost every HP iPaq and HTC PDAs/phones.

Changes:
- follow battery class changes (get rid of vast amount of macro-created
functions).
- cleanups
