Took me a dammn while to get wcpufreq to work on my i7 with intel_pstate
but here we are, it should work on any "iX" processor

wcpufreq

the intel_pstate driver was pretty straightforward on my machine:
- powersaver
- performance

and wcpufreq didn't liked that and insisted on using the old way of freq 
scaling. With this small set of changes it should actually work on the newer 
intel CPUs and won't try to load stupid shit like the amd_freq_sensitivity 
driver (duh)
