I can tell you this much, from using a Thinkpad X22 with Fedora Core 3. 
You may notice different results on a different machine.  (Who knows - for
another laptop brand, suspend to ram might actually work :) )

- ACPI suspend hangs the machine.

- Fedora out-of-box doesn't support software suspend (to disk) - for that
you may need a kernel recompile.

- APM suspend (to RAM) won't work unless you stop
the PCMCIA service before suspending, and even then it won't wake up
sometimes.

- APM hibernate (suspend to disk) works nearly flawlessly after
creating a hibernation file with tphdisk.  You don't even have to stop
PCMCIA.  The only catch is that you must mute and unmute sound with amixer
after resuming.
