Yep, I think I've identified the problem.  The chips are in DPA mode.  The 
manual talks about moving jumpers J11-14 to their alternate position, but 
I can't find those anywhere.

And looking at the schematics it appears that on the Rev E boards, at 
least, the DPA config pin is hard-wired :-( :-( :-(
