Still, they're cousins,
Identical cousins and you'll find,
They laugh alike, they walk alike,
At times they even talk alike --
You can lose your mind,
When cousins are two of a kind.

Good Call.
If black and cinnamon weren't versions (or alleles) of the same gene, when you crossed the two you'd get all Normals. But you don't-->you get supers as you pointed out. The mutations fail to complement (i.e. produce normals) so it's the same gene that controls the two forms.
Lineage could mean several different things at the molecular level....maybe black pastels are just slightly different mutation in the same gene as cinnamon. Maybe Cinnamons have a different overall genetic background than black pastels.
You can distinguish these two possibilities from one another by taking a super produced by a black x cinnamon cross and crossing it to a normal. If you get blacks and cinnamons (you'd expect ~50% of each type) then you can rule out background effects.

Well, if you produce a super from a black x cinny cross you have already proven them to be homozygous (since a black x cinny cross, if the genetics were different, couldn't produce homozygous, or "supers" anyway).
Although, it is plausible that a double heterozygous black/pastel would be all black (if the genes are different), and thus appear to be a homozygous cinny, I'm certain the "super" form of the black/cinny has been bred to a normal, resulting in 100% morphs. That dispels almost any possibility of two genes at work, since double heterozygous codoms would produce normals, blacks, cinnys and black/cinnies.
I think Adam put it the best (via Tracy)... a black pastel and cinny pastel are no different from each other than a lemon pastel and a jungle pastel are different from each other.
But back to the OP... Ed, hurry up and make some Silver Bullets so I have something to drool over.
