I don't think it's possible, now I have 2 Freebsd systems and they
have different slices. It was late, so maybe on my account on sever
I've mixed configs, or, I don't know...

Sorry if it's stupid question, but could you tell me how to use this patch?

I've noticed that always after installation on "clean" system acpi
shows proper battery state( 8.0 and 8.1), but when I install xorg,
dbus, kde and reboot I will be dealing with acpi errors... again.
