With apm, it would be controlled by your bios and need (usually) a specific hibernate partition.
With acpi, it is done entirely in software. Either might or might not work.
Check /proc/acpi/power, especially the contents of "state". My lappie has the choices standby, mem and disk. Standby is a light suspend-to-ram; power is on, but is consumed very sparingly, ideal for a laptop ;)
Mem is supposed to be a heavier suspend-to-ram; it doesn't work for me.
Disk is most interesting; it saves your RAM into your swap and turns off. And on the next boot, the kernel sees this and continues normally. This requires adding resume=/dev/hda2 (or whatever your swap partition is) to the boot line, and making sure you have more swap than ram.
To trigger one of these states:
|sudo echo -n "standby" > /proc/acpi/power/state|
There's no such thing as life. Those mean little jocks invented it ;)
