You should try posting this to the freebsd-acpi list instead, including 
the full /var/run/dmesg.boot and details of your hardware (make, model);
I've not seen an 'INSYDE' ACPI BIOS before, but others may know of it.

The first ACPI Error message indicates not being able to access the 
Embedded Controller (EC), which among other problems that may cause, is 
why ACPI can't get information on your battery status [\\_SB_.BAT0._STA]

There have been recent commits to acpi_ec.c and other ACPI code - you 
could try booting 8.2-BETA1 from a CD or memstick to see if that helps? 
- otherwise you're likely to be asked to provide info on your machine's 
ASL etc.  Best to be well prepared first by studying:
