Shimon, thank you for the detailed response; I am, as you probably suspected, very familiar with cultural relativism, which is why I asked this question in the first place; as to Freud's awareness to these issues, I would venture further than examining his cultural reservoir in light of the city of Vienna, but in the context of European well-educated men of the 19th century. I guess what I'm asking, to be put rather simplistically, is whether Freud (or: "a Freudian") would expect a Mongolian toddler, living in a nomad tribe on a mountain, who had never heard of Oedipus, to want to sleep with his mother and kill his father.
