Well, I now have that new HDMI->DVI adapter, and my video now works!
Both the console and X Windows (running XFCE) work fully.  There must
have been a dodgy connection in my old adapter, possibly in a timing
twisted pair, or something like that.

As always, after solving such a problem, one wonders why it took so long
to fix.  I was convinced it was something in the motherboard's firmware,
and it took an actual demonstration of it working on an HDMI monitor to
persuade me otherwise.

Anyhow, now to finish setting the machine up, in particular getting an
email server installed and configured.

Many thanks to the people who helped me diagnose the problem,
particularly Michael and Dale.
