Yes, thank you all very much for the suggestions.  These
commands, confirmed in the page modesetting page, did the trick:

    echo 0 > /sys/class/vtconsole/vtcon1/bind
    modprobe -r nouveau
    modprobe nouveau

I was already blind on the console, so I logged in via ssh to do
the above commands.  After reloading the module, the console
returned to full, normal function.

Thank you,

Robert Riches
