Ok, with that change, I get the following:

berr-reporting on:

And now lots more of this last frame repeated, until the controller
decides to stop. Seems fine. It has always done this.

berr-reporting off:

  can1  20000004  [8] 00 08 00 00 00 00 60 00   ERRORFRAME
  can1  20000004  [8] 00 20 00 00 00 00 80 00   ERRORFRAME


Same as before. Excellent.

Ok, I'll wait a few more days before pinging him again. He's CC'd on all
of these emails anyway. :)

Thanks for all the help,
