I have a book which describes the specific differences in the 601
as compared to the standard PowerPC architecture, and it looks like
it won't be that hard to fix things up.  [Chuq -- I should photocopy
the relevant sections for you]

Also, at least a couple of developers (Chuq Silves <chs@netbsd.org>,
and myself <thorpej@netbsd.org>) have 7200s (though mine is currently
in storage right now -- I'm in the process of moving :-)

Well, I hope to fix this soon.  I'm looking for a new project to help
pass the time of my 2 x 1.5 hour train commute each day :-)
