You don't necessarily want to take that driver as a good example of
what's needed to write an ACPI driver.  Actually somebody else just
pointed out the same thing to me earlier today.  On the systems I work
on, I use serial console, so it's pretty much mandatory to have 8250
built in and hence the remove method never gets called ;-)

Take a look at something like the button driver instead.
