I didn't get it to work with DISPLAY and XAUTHORITY either, so I 
reverted to my rough method

NEPOMUK="org.kde.nepomuk.services.nepomukstrigiservice"
SUSPEND="/nepomukstrigiservice org.kde.nepomuk.Strigi.suspend"
RESUME="/nepomukstrigiservice org.kde.nepomuk.Strigi.resume"

case "$1" in
  on|resume)
    CMD="$RESUME"
    ;;
  off|suspend)
    CMD="$SUSPEND"
    ;;
  *)
    echo "Usage: $0 {on|off}"
    exit 1
    ;;
esac

. /usr/share/acpi-support/power-funcs

for x in /tmp/.X11-unix/* ; do
  displaynum=`echo $x | sed s,/tmp/.X11-unix/X,,`
  getXuser
  if [ x"$XUSER" != x"" ] ; then
    sudo -u $XUSER dbus-send --session --type=method_call -- \
      dest=$NEPOMUK $CMD
  fi
done


I'm using sudo instead of su because, on my system, su triggers an 
unecessary password prompt from libpam_mount.
