:answers in case anyone else hits this problem?

  Having done some more digging, the official answer is to always use the
  PBXGA-BA/BN or PBXGA-CA/CN ZLXp-E* series graphics controller cards only
  with a DIGITAL-supplied BC13L-10 or BC14J-10 series video signal cable.
  What you are seeing -- the ghosting -- can be a known and expected problem
  if a another cable is used. If you purchase one of these graphics cards,
  you will want to ensure you receive the cable.

  It would not surprise me that the cables manipulate the ground, but I
  do not know that -- and I haven't dug through my stash of cables to see
  if I have one of these available for some continuity testing. I'm also
  not in a particular position to recommend a solution based on soldering,
  but y'all probably guessed that already.

:Now I have just one remaining question: Why does "Style Manager - Color"
:not allow me to change colors (the "Modify" button is greyed out) with
:the ZLXp-E2, but does allow it with the Elsa and ATI boards?

  Donno. Not enough planes?
