I doubt that I could persuade Dieter to do anything at all, but if I
could, I would persuade him to fix the bug, rather than just updating
the documentation to mention the problem.

This will never happen, of course. They're too busy developing a
friggin' Nintendo controller and the like.

If someone works out a schematic of either your solution, or the
"split" approach, I'll buy a spare A150 and give it a try. Its way
beyond my capability to work it out myself.
