Everybody seems to be missing the point.

We don't make new drivers "default y" (or, in this case, "default SERIAL_82=
50".

It does not matter ONE WHIT if you have a serial device in your
machine. If your old driver was enabled and worked for you and you
used it daily, that is ENTIRELY IMMATERIAL to a new driver, even if
that new driver then happens to use some of the same infrastructure as
the old one did.
