Not fixed (not by a long shot), but maybe a hint.
After further googling, I took a look at
  /lib/modules/6.18.20/kernel/drivers/mouse/   2026 non-working
versus
  /lib/modules/5.13.11/kernel/drivers/mouse/   2021 working
And they're indeed different. So I tried a little experiment:
  cd /lib/modules/6.18.20/kernel/drivers/      in new 2026 partition
  mv mouse mouse_6.18.20
  mkdir mouse_5.13.11
  rsync -av /mnt/lib/modules/5.13.11/kernel/drivers/mouse/  mouse_5.13.11/
  ln -s mouse_5.13.11/ mouse
That is, I made a copy of the old/working mouse drivers
in the new/non-working drivers/ directory, and linked to it.
Then rebooted.

Are you anxiously waiting to hear what happened with bated breath??? :) ...
  Well, mousepad is now recognized, sort of.
  If you touch it in any way at all, mouse cursor uselessly jumps all
  over the place, and continues to jump until you remove your finger.

The corresponding psmouse sources seem to be in
  /usr/src/linux-6.18.20/drivers/input/mouse/    (or linux-5.13.11)
The psmouse.h headers are identical except for one line:
  struct psmouse *psmouse_from_serio(struct serio *serio);
  is at line#133 in the 6.18.20 version, but not in the 5.13.11 version.
The psmouse-base.c files are more noticeably different,
and beyond my ken to try to explain here.

Don't know what any of this all means, but hoping it's
a step in the right direction.
