After more investigation, I would rather suggest using /boot/loader.conf.local and add the following : 

cpufreq_load="YES" 


You also need to add : 


kern.timecounter.hardware	 i8254

in  System: Advanced: System Tunables


and then start/activate PowerD + reboot


Then your device should be ready to limit it's power consumption and "save the planet" ;D
