AFAIK, it is only ACPI that allows this to be done, as ACPI gives the OS direct
control of the hardware in the system, whereas apm is done from the BIOS. Feel
free to correct me if I am wrong :)

As for using the power switch to suspend rather than shut down, this can be
done with acpid, and an event handler in /etc/acpi/events. You may already
have sample events set up there all ready, if you have acpid installed.

It is simply a matter of capturing the power button, and running the command of
your choice, which could suspend the system for you.
