Interlan, 11/70 & 2.9?

I am trying to get an Interlan interface working on a PDP 11/70
under 2.9BSD.  As soon as the Interlan board gets some host memory
to DMA stuff into, the system goes to pieces.  I haven't done
a board swap yet, but I doubt that is the problem.  

This code worked on an 11/45, so I suspect a problem witht the UNIBUS
mapping code in the network buffer management.  Nothing glaringly
obvious jumps out of the code (yet), so I assume that the bug is subtle.

Ok there, 2.9 fans!  Surely someone has invented/fixed this wheel already,
so help would be appreciated (Not that I don't LOVE kernel memory
management debugging :-]).
