I wish video cards had unique numbers, kind of like ethernet MAC

In any case, I used pathnames that are bound to PCI slots, pathnames
already supplied by the system.  That seems better than UDEV rules for
two reasons:

- I don't have to muck with scary udev rules.  For example,
  user-supplied udev rules must mesh with system-supplied ones, and
  system -supplied ones may change without notice.

- PCI slot numbers can distinguish between otherwise identical cards
  whereas (I assume) udev rules cannot.  This matters because two
  identical cards may be hooked up to different signals

Thanks for the help.
