i want to install vanilla kernel from apple, my question is where do i get it?

i had 10.5.6 ComboUpd but don't know which files needs fro it, i know about mach_kernel, system.kext, but what else? dunno.
besides i'll find out if my build supports Vanilla kernel, but i think that will be a test, try approach....

if someone knows how or what trick to do to install Vanilla kernel? and the files, please?

Right now i will try extracting mach_kernel, mach_kernel.ctfsys, system.kext from the update i try with that. Not so sure why i'll get after installing
