I've an 6710b and experienced similar "shutdowns" :)
Try this:
/etc/rc.conf:
devd_enable="YES"
/etc/devd.conf:
notify 10 {
match "system" "ACPI";
match "subsystem" "CMBAT";
match "notify" "0x80";
action "/etc/acpi_battery 30 5";
};
/etc/acpi_battery:
#!/bin/sh
warn_level=$1
shutdown_level=$2
life=`sysctl -n hw.acpi.battery.life`
if [ "$life" -lt $shutdown_level ]; then
echo "shutdown"
/sbin/shutdown -h now
elif [ "$life" -lt $warn_level ]; then
echo "warn"
fi
There might be an easier way, if there is a different notify command for
battery low. I guess 0x80 is just battery info.

Michael
