I dont know where to put all the files that he has included!
Use Kext Helper b7 to install them. You can get from Multibeast or here: http://cheetha.net/
Drag and drop all the kexts into the text box, type your password and hit enter.
Though personally, I don't use the AppleHDA kext, causes kp's for me. I use VoodooHDA 2.7.2 instead. That can be found in Multibeast. Remember to repair permissions after installing kexts.
