Hi Marcin,
i have a 2011 Macbook Air - Processor 1.7GHz Intel Core i5
Purchased 2 weeks ago. I would be glad to help if you need beta testing.
Has anyone tried xnu-speedstep-air?

I'm looking for some volunteers with MacBook Airs Revision B and Revision C. I don't have these devices so I'm unable to make sure that everything works correctly. If you want to volunteer to beta test you will get the solution for free and not have to wait for Coolbook to get done (if it ever does).
Seems exactly what I need. Could someone a bit more technical compile it and make it a bit more user friendly than compiling source with Xcode) 😉
First thing, I'm using 10.7.2 11C48.
First I installed coolbook (the newest version). Then, deleted the extensions AppleIntelCPUPowerManagementClient.kext and AppleIntelCPUPowerManagement.kext from /System/Library/Extensions.
Then I installed kexthelper (http://cheetha.net/) and installed this extension:

#!/bin/sh
if [ $# -ne 22 ]; then
echo 1>&2 Usage: $0 expected 22 arguments
exit 127
