:-). I made a tool to switch between 4.1 and 4.3V and display
estimated charge. It is at

https://github.com/pavelmachek/unicsy_demo/blob/master/bat/batman

. I usually let it charge to 4.1V, then tell it to boost to
4.3V when I anticipate the need for battery life... Likely better
solution would be "I'd like this battery to be full at 8am".

I believe the steps are:

1) Verify pulseaudio works on n900, in full duplex mode, and verify
the latency.

2) Verify the voice call quality is acceptable (it was not for me).

3) If biggest problem is CPU load, that probably can be fixed. But I
did not know how to fix 2), and did not verify 1).

I have this: Also not sure if it is useful...
