They both have a via-pmu at 16000 node. I'm hoping someone has an original blue and white PowerMac G3. I would like the full device tree printout from it. The question I am trying to answer is does any newworld Mac have a via-cuda? If they don't, we know that it should be changed to a via-pmu at 16000 node.

Thanks for the info. Did you see any official documentation that said what model the mac99 machine was suppose to emulate? I guess it was the first Blue and White PowerMac G3 because of how close it is to the emulated model.
