We have NuBus code for mac68k.

I tried booting MkLinux on one a few years ago, it didn't get very
var IIRC. My 6100 doesn't seem to want to talk to the display now
so I can't check.

As well as MkLinux there is supposed to be support for NuBus PowerMacs
in the Linux/PPC tree <http://nubus-pmac.sourceforge.net/>.

The BootX bootloader for Linux/PPC is available with source, so could
be extended to boot NetBSD too. The first task would probably be to
make it build using MPW.

I haven't tracked down the source to the MkLinux Booter so don't know
if it would be better.
