As far as I understand, it only gets used at all on ARM for the
blkback=>qcow path, and has nothing to do with I440FX or other boards. 
i.e. it is a paravirt disk and nothing else.

xenpv should not be tied to i386-softmmu in the first place, and would
remove a very-WTF-worthy current state of things.  That said, I have no
idea how much effort that might be.
