Power is the correct way to awaken the system. If you have a "sleep"
key, edit /etc/acpi/default.sh to account for the power-button press
that shuts down the system. Something like:
case "$group" in
button)
case "$action" in
sleep)
touch /etc/.acpi_ignore_power
echo mem >/sys/power/state
;;
power)
if test -f /etc/.acpi_ignore_power; then
rm -f /etc/.acpi_ignore_power
>/dev/null 2>&1
else
/sbin/shutdown -h now
fi
;;
...
If you don't have a sleep key, put the above commands in a script and
call that instead.
Also, you could emerge sys-fs/hibernate, and edit
/etc/hibernate/hibernate.conf to use /sys/power/state. Hibernate can
also take care of switching to a text console, hacking video modes if
necessary, locking the console or X desktop, and so on.
I actually use hibernate with two different configurations,
hibernate.conf and standby.conf, depending upon whether I press the
sleep or power buttons.

Some video drivers do not restore correctly. Use hibernate, or text
console, or google 'vbetool'.

Which video card and driver? Are you using opensource drivers (which
usually work fine with power management) or proprietary ones?
