[FC2] How do I suspend?

I have a partial answer (to myself).

You can tell what sleep options your ACPI BIOS supports with: "cat
/proc/acpi/sleep". My Dell C600 laptop says:

S0 S1 S3 S4 S4bios S5

An S3 is a software suspend I believe. This is what I think I had going
before in RH8.0/RH9/FC1 when I hit the "suspend button".

In the 2.6 kernel with ACPI, you can start a suspend by doing:

echo 3 > /proc/acpi/sleep

But that is not the whole story. X on my system does not handle this
properly. Perhaps I need to do some sort of preparation before the echo 3?

I'm beginning to get the feeling that suspend has not quite been finished
in the 2.6 kernel.

I wonder why (software) suspend worked reasonably well for me in the
2.4 kernel of RH8.0/9 and FC1?
