It's too early for any announcements really, although *personally* I do not think it's worth it unless the last version (of the iBook) works w/o any bigger modifications with the PowerBook MorphOS version. Support for pre-2005 models is even less likely. Support for models without at least Radeon 9200 has no real chances of ever happening.
The final revisions of 1.33GHz and 1.42 for the 12" and 14" models, respectively, have Radeon 9550s, I think. I agree that supporting earlier models is probably not worth the effort, but I would gladly loan one of the aforementioned models to the team if it would lead to official support.
