How to properly use propertree to acomodate kext files.

So im having a problem, trying to get my trackpad to work, i think i have the files i need but i never get the trackpad to work dont mater what i do. Ive seen that using propertree could help acomodate the kext files in the order that they need to be, but everytime i try it, i get kernel panic, and like kext files like lilu, that i know it should be first, it gets placed third or even forth, so i dont think im using it as it should, does anyone14:577 01:174 OC: Prelinked injection ThanksVoodooRMI.kext\Contents\PlugIns\RMII2C.kext (V1) - Invalid Parameter
