I've been digging into this, and it looks like it's going to be more
complicated than what I thought. FreeBSD blkback is not prepared to work
with hotplug scripts so we also need to modify it.

I hope I'm going to have some time next week to prepare a patch to both
the FreeBSD kernel and libxl, sorry for the delay.

Roger.
