Well there is currently a thread in port-macppc about kernel startup and 
entry vectors. It seems that Louis Gerbarg from the Darwin project might
add NetBSD support to bootX. As fas as I understand, BootX launch a UNIX
kernel from the MacOS, and gives it a device tree similar to what we 
currently get from OpenFirmware.

See http://mail-index.netbsd.org/port-macppc/2001/04/24/0007.html

It seems to me that BootX support means that we would be able to boot 
NetBSD on machines without OpenFirmware too. Then this is a matter of
getting NuBus support from mac68k and 601 support from upcoming rs6000
port. 

How far this would be, I don't know. BootX support seems not that far away,
but I have no idea of rs6000 port status. Additionnaly, care should be
taken to ensure that 601 support for rs6000 would be sharable with other
powerPC ports. Then for NuBus, nobody said he would do it.
