Covered on the fedora-test-list :) The best way is to add the following
to your rc.local:
# turn on acpi subsystems
# contributed by Bill Nottingham in a post to
# fedora-test-list@xxxxxxxxxx on Mon, 29 Sep 2003
if [ -d /proc/acpi ]; then
for module in /lib/modules/$(uname -r)/kernel/drivers/acpi/* ; do
insmod $module
done
fi
