I have the glue, can detect the controller and devices attached, and can issue
commands to the controller.  What I can't do, though, is actual data transfer --
the 53c94 does not do PIO gracefully, and I do not quite understand how DMA
works in NetBSD/vax[1].

Matt Thomas said a couple of months ago that his version of the driver was
almost finished, so I stopped work on mine.  Maybe I should resurrect my code ...
