Добавьте параметр ядру intel_pstate=disable

перезагрузитесь и посмотрим результат.

О, помогло:
current CPU frequency is 800 MHz (asserted by call to hardware)

А таки intel_pstate у нас никак не использовать?
Пишут, что вроде thermald для этого нужен...

Для его использования ничего не
нужно - достаточно только драйвера.

при этом частота меняться не будет, но энергия экономится.
