Here is a complementary bash script which you can use instead of the
simple "echo mem > /sys/power/state". It restores the original display
settings after wakeup, especially the backlight, which otherwise is set
to the highest value (at least on my system). It assumes that Eva's
sony-laptop module is installed.

#!/bin/bash

# get current video

case $(</sys/devices/platform/sony-laptop/speed_stamina) in
(stamina)   videoId=00/02.0
            ;;
(speed)     videoId=01/00.0
esac

# Save video state in tmpfile

tmpfile=/tmp/video_state
trap 'rm -f $tmpfile' 0 1 15
cat /proc/bus/pci/$videoId > $tmpfile
sync

# suspend

echo mem > /sys/power/state

# resume, reset video state

sleep 2
cat $tmpfile > /proc/bus/pci/$videoId
rm -f $tmpfile

Greetings,
