Again I personally recommend CyanogenMod version.

Partly referred to : http://wiki.cyanogenmod.com/wiki/Building_Kernel_from_source

Notice: Kernel Source Code is : https://github.com/CyanogenMod/samsung-kernel-crespo

configure file: herring_defconfig

Notice: Don't use the image pulled from the device, use the one in the installation zip file.
