So, last I checked, Linux ACPI didn't support suspend to memory or
suspend to disk; the software suspend patch is the only way to get an
ACPI laptop to do anything resembling sleeping. I was also under the
impression that this wasn't going to work for awhile; at least until
2.6. I admit I haven't looked at ACPI in a couple months, but last time
I looked, they were projecting that suspend./sleep wouldn't happen any
time soon.
