-Kext Helper b7 (for patching new kexts)
-Taruga's AppleHDA.kext patcher (in case you need to patch your AppleHDA.kext for any reason before starting)
-Kalyway Mac OS X 10.5.3 Combo Update (you can only use this if you have a SSE3 Intel CPU, and if you don't want to use the alternate guide)
-Mac OS X 10.5.X Combo/Delta Update (obvious reasons)
Do NOT ask me where to get these! You can get Taruga's HDA patcher somewhere on this forum. Just Googe Kext Helper b7, and you should get a good link. The updates can be found on Apple's website. Kalyway Combo Update can be found on [torrent site]. Just search for Kalyway Update 10.5.3 and you'll find it. NOTE: do not attempt this guide for 10.5.6. I haven't updated it to work for 10.5.6.
