Yes, but I am thinking that one user-mode X.org driver could work for
all systems that X.org runs on, but that kernel-mode drivers will vary
a lot, so several drivers must be written instead of just one.

Of course, the ideal solution would be a cross-platform device driver
ABI. But, what are the odds of that working?

Most of these issues aren't even a problem for most users, who
will only want to use simple pointer/keyboard/joystick devices.
That's why resolving the issues have been ignored for a long time,
and most people don't even try to use X for other devices.
