I beg your indulgence. If you don't have it to spare, just tell me to JFGI and
I will, but I see some humor and irony in my situation. Plus I like
reconnecting with old Debian colleagues.
I don't precisely know how to do this. I've never had to actually fight with a
modularized xorg.conf file before. I have, however, consulted xorg.conf(5) and
modesetting(4).
Here's what I think I need to do:
1) Create /etc/X11/xorg.conf.d. (done)
2) Write a file to put in there. (in progress)
3) Restart the X server. I enabled zapping[1] so this is easy.
The problem is that an Identifier is mandatory for the Device Section I am
writing, and I cannot tell from my Xorg.0.log file what identifier is
"autodetected". How do I figure this out?
I am attaching my untested conf file.

I did see that; thanks. That's the next problem I'm going to tackle after my
precious missing underscore. (My work habits involve maximized xterms and
vertically-split vim windows; those, combined with the monitor I'm using and my
aging eyes, mandate the 14-point font size.)
But in the meantime I did want to report that problem because frankly it's
insane to be dumping that much redundant crap into the log file. syslog has had
message rate limiting for decades, and the Linux kernel for several years at
least. Someone was not thinking.

[1] It's very nice to have this configurable via XKB and the
keyboard-configuration package these days!
