Default Cm11 CPU governors

Hi,

Two questions;

* How come there's no interactive CPU Governor in CM11? The standard pegasusq causes audio crackling/stuttering when the screen is off. If I switch to ondemand the stuttering is gone but the power consumption is higher. On my HTC Ville running latest CM11 I have the option to change to interactive. Do I need to flash custom kernel for more governors?

* None of the standard CPU Governors in CM11 let's me set minimum/maximum CPU frequency, the buttons are greyed out. I can change frequencys on my Ville in the same options menu.
