Thanks!

Well... the values are not really N900-specific. They should work well
on anything with lithium battery, because they basically depend only
on battery chemistry.

I guess I can simplify patch to work with battery voltage only --
that's what hardware battery protection does -- and make shutdown
voltage configurable ...?
