ACPI defines two different battery device interfaces: "Control Method" batteries, in which AML methods are defined in order to get battery status and set battery alarm thresholds, and a "Smart Battery" device, which is an SMbus device accessed through the ACPI Embedded Controller device; this driver knows how to attach to the former sort of device. As a total kludge, since we haven't wired things up to sysmon/envsys yet, we report battery status through a once-per-minute kernel printf, so don't use this driver yet if you want your disk to spin down. Motivated by and tested on Sony PCG-R505TL laptop, which has nonfunctional APM. configure as: acpibat* at acpi ? Sample output: acpibat0 at acpi0: ACPI Battery acpibat0: Sony Corp.
