This is a temporary bandaid to get vidconsole working again without

options USERCONFIG being present.  Due to the lack of early boot hints
neither sio or sc would succeed the console probe.  If USERCONFIG was
active, there was a second cninit() after userconfig had run and that
happened to make the console selection work.  If you left out USERCONFIG,
you would end up with no console at all. :-(

This needs a proper fix, especially when sc looses the "at isa" hint.
But for now, this works.
