I've replied to Jan's patch as well. IMHO having the option but
leaving things broken without the option set is a bad user experience
as we don't have a way to tell the user when the option is needing to
be set during install. Asking users to see if Xen crashes during boot
is a bad user experience as part of the setup. There should be an
automatic fallback to try enabling the legacy option if things don't
work without it.
