    Something I just noticed in the output that I had not before is that
    the boot loader appears to be reinvoked, either restarting or jumping
    to itself somehow.  ISI/UCB had a problem like this long ago as well,
    I think it was even on Sun machines.

    Keith Sklower, do you remember how/if it got fixed or how you worked
    around it?

It had to do with a patch to the very low level boot stuff, originally
to fix a problem with a hardware bios call overwriting part of the stack,
and Mike provided a working around originally for the emluab-specific 
pxeboot (that had bootinfo stuff added).

The same file gets incorportated when /boot/loader gets compiled, and
I replaced /boot/loader on our FreeBSD62 images.

I don't recall which two files in /sys/boot/stand/... got modified.

Ironically enough, I'm swamped with classes today as an *undergradute*
music major (going back part time as a 2nd bachelor's student), and just
quick looking for fires to douse between classes.
