That seems to work to some degree.

Caution: last time I did that on the new battery pack, it reduced

Not without some work (pmud doesn't know about battery voltage
currently). There's some differences between kernel PMU code and pmud
anyway so I'll need to touch that code perhaps (did anyone ever notice
discrepancies between charge level reported by pmud and

We can try that, sure. Needs some reworking of the sleep logic, but might
help with old batteries.
