Well, the problem is a little bit different in your case.

The smart battery stuff via ACPI is still under devellopment because
it is under normal ACPI specification, and this will be likely
merged this year (at least in -current).

Your problem is a real bug in the DSDT, and require a workaround which
in any case will break ACPI specification.  For now, I'm not sure if
such workaround will be done, and if one is written, we have to check
twice it will not break too much the ACPI interpreter.
