The kernel needs init.d support, which I believe most ''aftermarket" ones do, if not all. Only ones that dont are usually the 100% stock ones.
You need to decompile the kernel, and edit a couple scripts to get it to work if it doesn't already. The kitchen will do it, but its kinda a pain if our don't know what to do.
Edit #1: Idk man. From ripping through your mod and having recently gone through all this. Pretty positive this won't work on a stock kernel unless it's modded. And the files are a little off from everything I've looked into doing my own homework on it.
Edit #2: I think I see what you did and I didn't know what that file actually was (used to it being named differently) and that this process was even possible. Believe your using "post boot" to run init.d, correct?
