battery* at pmu?
The battery driver provides support for batteries and hardware sensors found in 1st generation PCI-based PowerBooks, currently it only exports a few sensors via the envsys(4) interface, including battery charge, volt- age, CPU and battery temperature and AC power availability.
envsys(4), pmu(4), envstat(8)
There is no APM emulation right now and the battery current sensor may return misleading or wrong data. This driver is considered preliminary and may be replaced at some point. NetBSD 5.0 April 2, 2008 NetBSD 5.0
