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.
