Well, today I've done a double downgrade:

- in my QtMoko codebase, back to

- in my build, back to the "old way" (as described by
  https://github.com/radekp/qtmoko) toolchain, and using
  -force-build-qt.

The result is that my battery seems to be discharging at a normal slow
rate again.  (With the default Finxi theme, I still have all 5 battery
bars after 3.5 hours mostly in suspend.  Whereas after upgrading as
above, I would have lost at least half the battery in the same time.)

So I think my battery is OK, and that there's definitely a problem
somewhere in the recent codebase and/or toolchain changes.
