devd can already do this..
Create a file for /usr/local/etc/devd (doesn't matter what it's called)
with this in it..

notify 10 {
	match "system"	"ACPI";
	action		"/usr/local/bin/acpi-ev $system $subsystem $type $notify";
};

The script will be called with "ACPI ACAD _SB_.AC__ 0x00" on power failure 
and "ACPI ACAD _SB_.AC__ 0x01" when connected.

(It is easy to call logger $0 $* in your script to check various events out..
