I'me using ACPI 

>   * 'sysctl -a | grep -i acline' when AC is plugged and pulled.
robert at bifur$ sysctl hw.acpi.acline
hw.acpi.acline: 1

pulling ac out... 
robert at bifur$ sysctl hw.acpi.acline
hw.acpi.acline: 0


>   * 'apm | grep AC' when AC is plugged and pulled.

robert at bifur$ apm | grep AC
AC Line status: on-line

pulling out ac
robert at bifur$ apm | grep AC
AC Line status: off-line

It seems i get also a lot of:
 rtc: 100 > kern.hz: Timing will be inaccurate, please increase hz.

when using the ichctrl ...

Probably due to the fact the clock freq is changed... 

If you need more info i'me willing to help
