The higher load address of the first stage went in on 22nd February, but
that was still old bootblock code.

The code is in there, but I was thinking of garbage collecting it at
one stage.  Look around line 287 of sys/arch/pmax/pmax/machdep.c for
details.  I can't remember the last time I tested it, but I don't think
I've changed machdep.c since then...
