Anyone got any thoughts apart from just putting in the above kexts from XPF, unmodified? Come on guys, I'm sure lots of you are OS X gurus, please don't be afraid to throw your ideas in the ring! I'm still a little unclear which kext(s) exactly are the ones that OS X looks for when it starts to boot and panics if it can't find one relating to your system? (unless it's the GossamerDeviceTreeUpdater one, although isn't changing the Device Tree just changing the info passed to the Installer eg the model ID, or does this also load drivers for the Gossamer?) I would definitely not need any from the Tiger disc as well as from XPF?
