Well, the current situation is such systems are unbootable without this
fix, so the pain from bumping for ABI sounds pretty tame in comparison. :)

I suspect, though, the boot halting segfault is probably a bug that can
be fixed elsewhere without supporting 32-bit domain devices. I'll see
if I can confirm that to be the case.
