Well, I'm not a generally patient person when it comes to things like this, so I went ahead and ordered a battery listed for the first generation 17" Intel MacBook. I decided to give it a shot, since it was only $60 with shipping and taxes. The model number is MA458*/A, or at least that is the compatible model number that the battery company is using. I'm not sure where it is being shipped from, either a warehouse in Calif., or it may have to come from China, so it may take a few days, or a month or more. I'll let you know if it fits into my G4 Powerbook.
