Well I'm only just finding my way round the sources but it seems to
me that this is sensible. There are just so many places that would
need changes to support the NuBus machines. One shared driver
that comes to mind is the Valkyrie video chip, available on both
NuBus systems and PCI systems. In the mac68K sources this is
detected as an obio device but the roughly equivalent code in the
macppc sources assumes Open Firmware support currently.

It could be changed but I think the kernel would grow quite

Just my thoughts...
