Would it?

It's present in OpenFirmware too, in all the places it should be
(/pci/isa/serial at 2F8 or something, if you set the output to serial
it should be there too, but of course then stdout is serial and
the code below is going to fail :)

Anyway. I am going to attempt to find a Mac I can start building
things on. I always wondered how on earth I could get a FreeBSD
or NetBSD port going when I need a working port on the same platform
to do it. I don't even have a PC I can shanghai for the task right
now.

Do they run in PearPC or so?

That's all present.

What about a text mode (just using stdout to print strings)?
