when you are in the install DVD from boot, copy the IOATAFamily.kext to the desktop of your installed system. Also, copy the AppleNForceATA.kext file over as well as it appears to be used. I am not sure (since I haven't used Zeph's rev2 DVD) but is there a few difference between the two AppleNForceATA.kext files? I would also look inside the IOATAFamily.kext file (right click, show package contents) and navigate to Contents/Plugins to see what else is located within this file... usually there are more ATA files placed in there.

EDIT: Also see if the AppleAzaliaController.kext file is needed. These are the primary differences I am seeing.
