You're right. Here's what I'm playing with right now:

It'll do the following:
% man mcd
Formatting page, please wait...Unknown FreeBSD version ``1.0.'' at line 155
Done.

An mcd driver appeared in FreeBSD 1.0.

I do think that we should change .Nx and .Ox to just print their argument
and not print any errors, since it's not likely that we'll write man
pages with those macros (just import them).
