I don't think we can fix them.  There's no pc98/include/param.h.
There's no pc98/include at all, but instead it uses the i386 ones.
But we could add the right goo there.

I don't think there will be another IA32 port ever.

However, we could define something like PCAT for FreeBSD/i386.  But
that also is unsatisfying.

I don't think that we can do the enumeration of all possible
architectures well enough to make things work like you'd like.
