Possible. It's optional (Power Management options -> CPU frequency
scaling -> 'ondemand' cpufreq policy governor) and it's marked "If in
doubt, say N.", so the Fedora people might have deactivated it. If
you're lucky they compiled it as a module (probably cpufreq_ondemand.ko
or ondemand.ko), otherwise you'll have to build your own kernel.
