I noticed your question concerning apm while searching the internet for something else, but I can help, I think.
Are booting with apci=off ?
If so apm will be loaded. If not, acpi is used.
FYI: check /etc/grub.conf
title Fedora Core (2.6.9-1.681_FC3)
kernel /vmlinuz-2.6.9-1.681_FC3 ro root=/dev/VolGroup00/LogVol00 acpi=off rhgb quiet
It makes no difference FC2 or FC3.
