Yes!  That works!   I had even tried re-doing boot0cfg before, but that,
obviously isn't the answer.

no output whatsoever, it would appear to go the video console if you hooked
up the cables.  This was the case with all my hardware.

The first reboot would be fine into single user for make installworld, but
after installworld, rebooting resulted in the loss of the console..  That
is until I added the /boot/loader.conf entries.
