Twisted IT paired

I've spent last hour trying to make a descent init.d script 'new way' that's working properly so I can have x11vnc started at boot time.
Here it is:

#!/bin/sh
### BEGIN INIT INFO
# Provides:          x11vnc
# Should-Start:
# Required-Start:    gdm3
# Required-Stop:
# Default-Start:     5
# Default-Stop:      0 1 2 6
# Short-Description: x11vnc server
# Description:       Debian init script for the x11vnc server
### END INIT INFO
#
# Author:       Anton Valqkoff < anton  valqk  com >

test -x $BIN || exit 0

if [ -r /etc/default/locale ]; then
  . /etc/default/locale
  export LANG LANGUAGE

                log_daemon_msg "Starting $SERVICE server" "$SERVICE"
        set +e
                start-stop-daemon --start --pidfile $PIDFILE -m --background --exec $BIN -- $OPT || log_end_msg 1

        echo "Usage: $0 {start|stop|restart|reload|force-reload|status}"
        exit 1
