So if we actually have a user, and it works, then no, we're not
removing EISA support. It's not like it hurts us or is in some way
fundamentally broken, like the old i386 code was (i386 kernel page
fault semantics really were broken, and the lack of some instructions
made it more painful to maintain than needed - not like EISA at all,
which is just a pure add-on on the side).
