Need working yaboot.conf and xorg.conf for Powerbook G4 Ti 9.04

[mattppcintel]

I recently upgraded my Powerbook G4 Titanium II from 8.04 to 9.04 and all of the sudden, X WONT START!!!! I had almost the identical problem upgrading from 7.10 to 8.04 (http://ubuntuforums.org/showthread.php?t=1006992) and eventually found a working configuration. Unfortunately that working configuration no longer works. If anyone out there has a working yaboot.conf and xorg.conf for a system with the same, or similar hardware please post it so I can use it.

Model: Apple PowerBook II G4 Titanium 550MHZ
