Last I heard, the mtDNA evidence was against that hypothesis, actually. Is there something in the last year or two that got published I don't know about?Also, there's solid evidence now of interbreeding between modern humans and neanderthals, so antiquated versions of the species concept probably need to go out the window. The only question I have is whether a full million years would be enough to make interbreeding impossible, or do these guys end up interbreeding with us as well.
Couple of skulls in Europe with jaws and teeth that have a very intermediate sort of structure, from around the time modern humans moved into the area, and associated with known sites. Jury is still out on them. But knowing humans and breeding... if we have 2 fossils.... there were probably about 10,000 times that many.Last I heard, the mtDNA evidence was against that hypothesis, actually.

Of course, the humans of Medieval Europe won't see any of these races as "people", but as fantastic creatures of myth, legend, and nightmares.
