It's a kernel boot parameter, append it at the end of the "kernel" line in 
grub.conf

Another thing that I've noticed -- if you have a leftover /etc/X11/xorg.conf 
from the previous Fedora release, rename xorg.conf and restart, letting X 
start with a default configuration.

I haven't yet fully verified it, but even if I boot with the unmodified 
kernel boot line, after removing xorg.conf, it looks like power management 
also starts working.
