FOR EXPERIENCED USERS ONLY!!!
Thanks to: Hroark13, zcop, Koumajutsu, The~Skater~187, PlayfulGod, thachtunganh, Shabby and Interdepth. And the crash test dummies for putting their hardware in harms way Johnny424, Wetbiker7, thomasmbl, Slayer72.
DISCLAIMER: Extremely low or higher than normal frequencies may freeze your phone. Especially high frequencies (such as those enabled in certain custom kernels) have a risk of shortening the life of your phone. If your phone freezes, just yank out the battery. I CAN NOT BE HELD RESPONSIBLE FOR ANY DAMAGE THIS KERNEL MAY DO TO YOUR PHONE.
I have made a kernel that has been overclocked from 800MHz to 944Mhz (I was able to play angrybirds space with no lag, no reboots). Everyones phone is different an will respond as such to this kernel.
Our cpu Qualcomm S1 MSM7627-3 is recommended at a 600mhz (stock 800 speed could technically be seen as an overclock) so I would like to progress slowly upwards in frequency... hopefully twards 1000mhz

Installation:
1. Make sure you have a working version of cm7, cm9, or MIUI (if you are coming from another ROM allow the ROM to boot first!)
2. Reboot into Recovery mode
3. Flash the respective .zip
4. Reboot
5. Use Voltage Control to change your CPU governor to "Ondemand (or whatever you see fit)
**I cant stress enough, Make sure your ROM boots before adding this kernel**
Note: This kernel is based on the cm7 mapfix kernel. There is no need to install it. If you do it will remove oc
Changelog
Version 0.4
Changed max frequency to 946MHz (Improved stability)
Added I/O Scheduler -> Cfq
Tweeked OC script
Changed CPU Governor polling to 50 ticks (hopefully improves stability by increasing time between frequency changes)
Added Active Voltage Selection ::shrugs::
Added sd-ext version for CM7
Default frequency 800MHz
Changed default I/O scheduler to S(IO)
Version 0.3:
Added clocking slots up to 944Mhz
Added I/O Schedulers > V(R) and S(IO)
Added CPU Governors > Brazillianwax, interactive, scary, lazy, smoothass, savagedzen, interactivex, lagfree, minmax, smarassV2, and Lionheart
Version 0.2:
Updated to kernel version 2.6.35.14
Resolved bootloop some users were experiencing
Cleaned script and added parts from thachtunganh's script.
Added clocking slots up to 900MHz
Removed 19MHz slot (19MHz can still be used for power collapse if you have it enabled in your build.prop)
Version 0.1
Initial Release
I would like testers to file reports in this format:
Speed/responsiveness:
Battery life:
Phone temperature:
Screenshots:
The CTMOD/STOCK (halfassed ROM) kernel is nothing more than a kanged KoumaKernel 2.3
to configure sd-ext support you must visit his thread: http://androidforums.com/galaxy-prevail-all-things-root/429740-kernel-gb-koumakernel-2-3-a.html
DUE TO A BUG IN CM9/MIUI SD-EXT IS NOT SUPPORTED... YET...
