Doesn't scale very well as we add more frontends though.

I don't see a huge benefit in making it separately compilable anyway; 
it's pretty small, and I can't think of much plausible use for a Xen 
kernel without frontends.  (On the other hand, making all of xenbus a 
single module might be useful, so that a non-Xen boot doesn't have to 
carry it.)
