Touchscreen should be USB based. Check System Preferences, you should see an Icon call Ink. You should be able to get basic mouse movement, if not you could try a 3rd party software call Touch-Base. Your SSDT-UIAC is a big different from mine, I guess the touchscreen model is configure differently. You should use either SSDT-UIAC + USBInjectall.kext or USBPort.kext, not both. Also use ApplePS2Controller.kext or VoodooPS2Controller.kext, not both. How is your experience with VoodooPS2Controller? Looks like the version you're using is by Acidanthera.
