Hi misc!

I just got one of these babies as a present and put OpenBSD on it
right away. Everything seems to be running smoothly, with the single
exception of battery and ac status readings in apm(8):

Battery state: absent, 0% remaining, unknown life estimate
A/C adapter state: not known
Performance adjustment mode: auto (1300 MHz)

If however, I remove and reattach the battery, it's status is there in
all it's glory. I've poked around in acpibat.c and acpiac.c but my
experience with ACPI is pretty limited and I can't really make much
sense of it (yet). Has anyone else experienced this problem? Are there
any obvious things I can try to get things working? I'm currently
building a kernel with ACPI_DEBUG defined to see if I can get some
more information on what's going on.
