Building cpufreq modules into F16 kernel is it right or wrong?

Thanks, I will try makestep directive with F16 kernel.
This is workaround may work or may not because chrony not always available.
For example chrony can be not installed on Live images (not from Fedora) or
other systems which don't have chrony.

The real solution can be adding kernel parameter like cpufreq=disable
that can disable using built-in cpufreq modules.
