Here's a simple kernel for AOSP based ROMS like CM9 and AOKP. Works for my tab. Can't say how it will run for you. Let me know.

v2 - Big Update. There may be bugs or issues I haven't noticed on my device.

Added Wheatley Governor ~~and some associated CPUidle and C4 sleep patches to maximize effectiveness of the governor (thanks to Ezekeel)~~
- ~~allow cpu to go to sleep/deepidle while using hardware accelerated video/audio playback~~
- ~~enable powering down mpu logic during C4 / deep sleep to reduce power usage~~
- Doh. Forgot to enable them when building the kernel...
Other misc. tweaks to Cpufreq and governors
Set 150mhz fuse opp to 50 OPP offset for voltage stability at lowest frequency
Change 150mhz slot to 180mhz to prevent SODs
Lower mpu vdd max to maximum value allowed by omap twl
- Gets rid of errors and problems when using 1350mhz+
Removed Samsung's "Touch Boost"
- Before, every time you touched the screen, the cpu frequency would shoot up, whether it was needed or not.
Removed Samsung's CPU frequency limits and locks
Removed touchscreen factory debug stuff and an annoying debug that was notifying you every time you touch and lifted your finger off the screen
Fsync off to improve file system read/write performance
Probably some other stuff I'm forgetting...

MPU frequencies from 150mhz to 1350mhz
- 150mhz slot given unique FUSE_OPP for lower SmartReflex calibrated voltages seperate from 300mhz slot
- 1350mhz slot running at 1200mhz FUSE_OPP to keep voltages down
GPU overclocked to 448mhz
- 448mhz GPU slot using same OPP as stock 307mhz slot to keep voltages down
Undervolted across the board
- but really irrelevant due to SmartReflex calibrations
SIO scheduler
Lazy governor added
RCU priority boosting
Other tweaks
