Okay so I try to follow this guide but I'm not very mac savvy and get lost. Here's where I'm at now. I have snow leopard installed using this http://osx.mechdrew.com/guides/nbi3.shtml it boots fine but it doesn't have audio and the ethernet port doesn't work. I used kext helper to install the kexts from your guide once and that seemed to fix it, but then I patched it and it stopped booting up normally, it would start to boot up but then restart and get stuck in a boot up restart cycle. And anytime I've tried using kext helper to install the kexts from your guide afterwards it does the same thing without me even patching it. I just want sound and ethernet to work :\ any ideas?
