You want swsusp2 rather than straight swsusp :-)

It is generally more reliable in 2.4 than in 2.6.  Works with SMP and
Highmem and preemptible kernels and other nifty stuff.  I have it
working on my desktop and it's fine - BUT you have to be careful to
unload some modules before suspending and reload them afterwards.  USB
and PCMCIA are likely suspects here.

I've had no luck with ACPI, either on desktops (though what's the
point, really?) or on laptops.  Apparently APM works like a charm if
your machine supports it though...
