Hmm, well, I suspect in this case these boards exist to support really
ancient custom hardware.  If you are stuck with one of these, then manually
needing to fix up pnpinfo.c is probably the least of your problems.  However,
I strongly doubt that FreeBSD users are lining up to buy these motherboards
so they can use an ISA SB16 adapter with FreeBSD/amd64.

I was not aware of these boards previously, but I still doubt that pnpinfo is
relevant to any FreeBSD/amd64 users.
