Okay, But what happens before the SMBios gets populated for the first time...

I've already edited the SMBios.plist information to identify my machine as a Macbook Pro. Doing that should allowed switching the SMBios data to allow such things as Battery and Touchpad to appear?

If they don't, then what? I've tried editing it to different models to see what the net effect is, but it appears nothing really changes to allow to become active. So what trigger inside the set-up, determines the flavor of the system? How do I recreate that?
