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.

With regards to mac99 target I would rather be concerned with lack of /uni-n, as
darwin seems to check for this (it panics when checking machine type)

In function Core99PE::start it does a lot of stuff on this device, while
power management is just few lines:

This machine for example has it:
