Following your suggestion, I did try this; and there was no
change from kernel panic and reboot.

There was no prompt.

Personally, it's a bit embarassing to be so helpless that I am forced
to take a picture. I suppose if I could be certain about how to
compile bootblocks, I might be able to do something on the serial
console with a laptop.

But the one time I attempted that was a disaster. 

Is my speculation about the "...no dump device found..." correct? Is
it that swapon and multiuser has not occurred, and so there can occur
no dump to the swap space?

If any more damage occurs, ISTM that my entire installation will be
accessing a NULL pointer; the following message is from the most
recent dmesg, and is new:

warning: KLD '/boot/kernel.old.bootable/drm.ko' is newer than the
linker.hints file

Since my hardware appears to not work with the available source, who
knows how that will go?
