DESCRIPTION
     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.

BUGS
     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.
