Ugh. I'd love to see short jumps, but I do dislike binary rewriting,
and doing it at early boot seems really quite scary too.

So I wonder if this is a "ok, let's not bother, it's not worth the
pain" issue. 128 bytes of offset is very small, so there probably
aren't all that many cases that would use it.
