I confirm this working on 10.8.3 Mountain Lion, but you forgot to mention applying DTGP patch from tutorial by the link you provided.

Great Post! I will have to give this a try when I have some spare time. I hated fixing my dsdt, this would have saved me some time. I currently use VoodooHDA it was the easiest and works great!
