This is a settled question -- these are all variations on the case of
the Bnei Rhenus, who were known to eat what we hold to be chelev
de'oraita.  Because they relied on a legitimate minority opinion, the
SA says one may eat at their homes, from their fleishige kelim, relying
on stam kelim einan bnei yoman.  Obviously one could not eat a dish that
might contain this chelev, but one could eat other meat.  Kol shekein
someone who follows a legitimate opinion permitting an issur derabbanan.
