Hello Matt, There are two independant software 'suspend' (ala suspend to disk) modules in rescent kernels (read 2.6) - swsusp and pm_disk. You could read the documentation in power/swsusp.txt (kernel docs) for more information. In two words - by using /sys/power/state you are trying to use pm_disk, and swsusp by using /proc/acpi/sleep. I'm still using swsusp (success on my IBM Thinkpad R40, unstable) and waiting for swsusp2 (swsusp.sf.net) to appear in mm tree (which looks promising). Hope this helped somehow.
