Here's the script. It seems to work.  For some reason, although 
xscreensaver reconfigures the DPMS settings, the new settings are not 
honoured. This is a workaround.

[rjn@mocha ~]$ cat bin/xscreensaver_dpms.sh

#Xscreensaver on Thinkpad X20 / Ubuntu Edgy doesn't play nice with DPMS.
#Even if we already did `xset dpms 1800 1800 1800`, xscreensaver
#somehow breaks this.
NUM=5   #Show this many hacks before powering off display.

echo "Running xscreensaver_monitor. Will force DPMS off after $NUM hacks 
have been shown."

COUNT=0
#Watch the xscreensaver status. When unblanking, the line will
#begin 'UNBLANK'
xscreensaver-command -watch | while read LINE; do
         if echo $LINE | grep 'RUN' &>/dev/null 2>&1 ; then
                 let COUNT++                     #increment count
                 echo "Blank detected. Count=$COUNT"
                 if [ $COUNT -gt $NUM ]; then
                         echo "Turning off DPMS"
                         sleep 1                 #just in case.
                         xset dpms force off     #force backlight off.
                         COUNT=0                 #reset count
                 fi
         fi
