Enable SpeedStep support on any capable Intel CPU

Be careful people.

it works.

This is my MacPro at home.

Just so people know, speed stepping occurs automatically, out-of-the-box by Apple.

I use the kext to stop it from automatically stepping down to a lower cpu frequency. (thank you to the authors!)
Why?
It's related to high resolution audio files and latency issues associated with playback and recording.

Those of you who wish to use this kext, I strongly recommend that you use smc fan control or equivalent.
CPU temperatures can get very warm very quickly under 100% load!

Be warned.
