As far as I can tell (by examining as many cars as possible) it's standard on 
all TORSEN ur-quattros.

I agree with your interpretation of the microfiche - as I posted here earlier, 
there are none of the cones/discs that one normally associates with 'limited 
slip' implementations - the major feature is the sprung pin that seems to be a 
centrifugally-operated detent.  Odd.  Research continuing.
