You can use either APM or ACPI for powermanagement (not both at the
same time). With FC2 the default is ACPI. When you use the kernel boot
option "acpi=off" - ACPI is disabled and APM is enabled.

Now the userlad 'apmd' can interact with the kernel & provide the apm
functionality (Fn-F4 for suspend etc..)
