Yes.

Following the recent discussion about USB keyboard support in SeaBIOS I
thought putting everything which all payloads share is the right thing
to do, no? Wouldn't we end up having clones of that stack appearing in
other payloads if we don't put it in a common place?

buildrom could do that automagically, though. But I'm unsure, too. I'd
really like to leave that up to you to pack the stack to a place which
seems appropriate. I just don't to get it lost, it was too much work for
that ;)
