Does your desktop PC shuts down the fan (cpu and power supply) in
suspend mode?

I didn't know APM can support a real suspend mode (like S3 in ACPI). I
thought laptops use some proprietary standards.

Is this the right place to ask APM specific questions?

I've tried apm -s and apm -S on my Asus P3B-F (Suspend to RAM
activated in BIOS) and my Asus TX97-XE.

I could return by pressing a key (IMHO real suspend should not power
the keyboard), open the CD and the fans continued...

One of these modes (-s or -S, I'm not sure) beeped 3 times and after
that the power-led flashed...

Can you please describe you APM-suspend-mode? Does your fan, keyboard
and CD stop?
