I have had good luck with FC1 and ACPI on my Dell Inspron 600M - I can 
"put it to sleep" thus (must run with root privs.):

	#!/bin/bash
         # shut down screen (activate screensaver)
         xscreensaver-command -activate
         sleep 2
         echo 1 >/proc/acpi/sleep

	# machine is now sleeping, pressing power button
	# will "wake it up"

         # next line gets the mouse back from X never-never-land
         /sbin/service gpm restart
         echo back from sleeping...
