The ACPI code isn't that old.

My guess is that a) the ACPI code in BIOS handles the _STA evaluation in
a strange way and b) our acpi_bat driver isn't graceful enough about a
failed _STA evaluation.

ACPI defines that a non-existent _STA is to be handled like a "device
present and operational" status. Now, an "insufficient memory" error
isn't the same as a "object does not exist" error, but maybe it should
be handled the same (so far we don't distinguish between errors anyway).
