First, before we start this, try "modprobe apm" (as root). Then try "apm". It may be that these are unloaded modules, in which case were done. Otherwise,
Install the kernel source. Now:
at this point, you have to find and enable acpi (or apm). If you enable both, acpi will run, apm will be disabled. It will be under power management.
make all modules
make install modules_install
now youre done. (hopefully). reboot and try again. You may need to reinstall your bootloader, am not sure if fedora kernel does that for you or not.
