I've been trying to figure out exactly what you mean with this
change.  I've decided you mean this is a line you need to remove in
order to build a kernel with wd.  Correct?

That might work, but I think it's a bit of a kludge.  Why not just
change the name of the driver to owd?  That way people will have to
make a conscious effort to stay with that driver, and we can issue
them with the dire warnings about the effects of doing so.

Remember this fix is supposed to be for non-CURRENT users, people who
are traumatized enough already.  A warning from config(8) would serve
a similar purpose.
