Please try method (6). It should work perfectly because it is the successor
for method (5) and works even without special patches for X.

First, boot into X and run the following script ONCE:
#!/bin/bash
statedir=/root/s3/state
mkdir -p $statedir
chvt 2
sleep 1
vbetool vbestate save >$statedir/vbe

To suspend and resume properly, call the following script as root:
#!/bin/bash
statedir=/root/s3/state
curcons=`fgconsole`
fuser /dev/tty$curcons 2>/dev/null|xargs ps -o comm= -p|grep -q X && chvt 2
cat /dev/vcsa >$statedir/vcsa
sync
echo 3 >/proc/acpi/sleep
sync
vbetool post
vbetool vbestate restore <$statedir/vbe
cat $statedir/vcsa >/dev/vcsa
rckbd restart
chvt $[curcons%6+1]
chvt $curcons

Unless you change your grahics card or other hardware configuration,
the state once saved will be OK for every resume afterwards.
NOTE: The "rckbd restart" command may be different for your
distribution. Simply replace it with the command you would use to
set the fonts on screen.

Please try my scripts and resport back.
