Well every PC is case by itself due to the components installed, not knowing the trackpad model I put the kext for ALPS trackpad, but obviously it does NOT work for you, I would need the original ACPIs to see clearly on the type of trackpad ... You may need different kext than the ones you use right now.
Use this EFI Debug in USB to extract the files I asked for and post them here, this if you want to improve the functionality of your Hack and as I asked already Ioreg is always needed as a verification tool
