xan, umm...this is something you should consult with eddie11c. I didn't compile the PPF, but do know for a fact that it did work for some people over at IRC. Did you select the appropriate drivers/kexts before you initiated the installation? It can also be that there are other fixes that need to be made to the PPF to see the dvd drive after the install. Can you see the drive in Disk Utility? What about System Profiler?
