Ok, thanks. In the meanwhile I have created a script which did the job.

#!/bin/sh
# /etc/pm/power.d/backlight
# set backlight brightness depending on power source
LEVEL_AC=15
LEVEL_BAT=12

BRIGHT=/sys/class/backlight/acpi_video0/brightness

case "$1" in
true)
level=$LEVEL_BAT
;;

false)
level=$LEVEL_AC
;;

*)
exit 0 # invalid argument
esac

[ "$(cat $BRIGHT)" != "$level" ] && echo -n $level > $BRIGHT

exit 0

And sorry for the OT posting.
