Yes, you need S3 suspend/resume.
On supported hardware (e.g. Sun desktop / workstation
systems and certain Toshiba laptops) S3 is enabled
by default.
On others it is disabled, but you can try to
enable S3 support by adding a line
"S3-support enable" to /etc/power.conf and
running the pmconfig command or rebooting.
S3 may not work, though, because some of the
drivers that are in use on your system do not
support suspend / resume, or there are other
issues that prevent entering S3 sleep state,
or prevent waking up and resuming from S3 sleep.
To get the system into S3 suspend state, use the
suspend button in gnome panel poweroff menu.
Or use the "uadmin 3 20" command from the
command line.

In case S3 works on your system, you should be
able to configure automatic entry into S3 sleep
state using the autoS3 and autopm commands
in /etc/power.conf - see man power.conf(4).
