Indeed.

I set CPUFLAGS+="-mcpu=601" and built a release from scratch in an attempt
to avoid any instructions that might not exist on the 601, but to no
avail.  I also turned on -DDEBUG for ofwboot with a similar lack of
success.  The same error happened at the same point.  Pointers to some
good places to put printf() in ofwboot would be appreciated.

Yes, as Marco suggested I did that when I rebuilt the world for a 601, but
I'm pretty sure that ofwboot isn't getting as far as trying to boot a
kernel.

I have considered this.  At the moment the 7200 and the 9500 are at a
storage facility that provides a work space but no internet connectivity. 
I may bring the 7200 home with me tomorrow so as to avoid wasting any more
CD-Rs :-)
