isnt there any mdb hack we could use? from the code i read not long
ago it seeems like everything is automatically done for us, we have no
way of setting the threshold in which it should scale down but i'm no
expert in kernel hacking so i might be wrong, according to the code
also there was an algorithm that prevented the processor to scale up
fast but that doesnt seem to be working here
from dmesg

it also seems a bit biased into using only either the highest or the
lowest available frequency
