Hrm...

Incidentally, Motorolla has quite a bit of documentation for PPC
processors on their web site - it's just a matter of finding the right
.pdf.

The NetBSD/powermac boot disk gives "code=FFF0700" when I try to boot the
7200 with it; the same disk works fine on the S900.
I wonder if PPC601 support was dropped in 2.4.x, or is somehow lagging
behind 603 & higher processors...

I wonder if the 1.3 first stage loader doesn't like the 2.0 second stage
loader.

Yes, I'm using 2.x - that's what gets installed by default by Debian
2.2r2.
Do you have the source for 1.3 someplace? I can't seem to find any
reference as to where to get it - all I can find is some LinuxPPC binary
RPMs that I can debianize with alien.
