This would be nice, but the main hurdles that have to be cleared are:
- dealing with 32-bit/24-bit/memory map issues
I don't know how bad this might be
- dealing with re-locating the boot program so the
kernel can be loaded at address 0
- dealing with various disk formats/machine configurations
- getting the information that booter now passes to the kernel

I need to look over the docs again, but I'm not sure that this is a
problem. If it is, we can certainly work with it, providing a minimal
partition map with a driver partition. I am willing to cede that much
to the Mac ROMs... ;-)

That's an issue now. The ROM patches from the MacOS aren't loaded into
NetBSD. (One of my arguments against using something like MRG in the
first place.)

Some sweat. That's about it.

I'd like to see it. It's just not a priority for me. ;-)
