Linux has numerous drivers for non-ACPI batteries, and I think we'd have
a much easier time just using (or if necessary hacking on) such a driver
rather than attempting to shoehorn the details into ACPI, particularly
since we don't get to write the BIOS for that board.

Take a look at the "sbs-battery" driver (CONFIG_BATTERY_SBS), which
might do what we want; it talks to a battery directly using i2c, without
using ACPI.

I can certainly take a look at the problem in more detail in a couple of
weeks. :)
