In theory, but the machinery to do this is a bit broken
and there's a bunch of cleanup and design fixes necessary
before we can turn it on for ARM. "do_unassigned_access"
is the QOM CPUClass hook for this, and searching the
mailing list archives will probably turn up discussion
about the fixes needed.
