Adding the following, as per Pauls instructions, seems to have worked on my system (as far as suspend goes):

brt=`cat /sys/devices/virtual/backlight/acpi_video0/brightness`
abrt=`cat /sys/devices/virtual/backlight/acpi_video0/actual_brightness`
if [ "$brt" != "$abrt" ]; then
echo $abrt > /sys/devices/virtual/backlight/acpi_video0/brightness
fi

I notice that my function keys (for brightness) no longer "work". When I use them, the brightness slider appears, but I can't adjust the brightness of the screen. I'm not sure this is related...
