CPU frequency doesn't drop below 1200MHz (like it used to)

[Nikos Vassiliadis]

Hi,

I just noticed that my CPU's frequency doesn't support dropping
below 1200MHz. It used to be able to go down to 150MHz, if I am
not mistaken. I'd like it to go down to 600MHz via powerd, like
it used to go. This is a month's old 10-STABLE.

This is the CPU:
 > hw.model: Intel(R) Core(TM) i3-3110M CPU @ 2.40GHz

Thanks in advance for any ideas,
Nikos
