BTW, I wonder why you need to change the BIOS options for intel_pstate to load.

It should be initialized before pcc-cpufreq (according to their
respective initcall levels), so in theory intel_pstate should be used
by default on the affected systems anyway.

What BIOS settings need to be changed for that?
