I looked at it once.

The big trick is that if you boot from BootX, you have no interface to
OF (but it hands you a copy of the OF device tree to look at), so any
NetBSD code that uses OF after autoconf time needs to be rewritten to
do direct hardware access instead.

In particular, this means video.
