Well, it's your (copy of) the file; I suppose you can do whatever you
want to with it.  :-)

I believe it will make some difference, yes.

As of FreeeBSD 6.0-STABLE, /usr/src/usr.sbin/config/lang.l (rev. 1.41,
last updated 2005/02/10 10:46:27) has tokens defined such as "cpu",
"device", "nodevice", etc., but not "nocpu". 

It might be worth adding, though.  Of course, some semantics would need
to be associated with it in config.y.

It might know what kind you havem but that's no guarantee that you plan
to run the kernel you build on the same machine.

Peace,
