I don't think it's going to tell us anything useful.  I believe that
we've not set up the cardmode Dino correctly to respond to iomem space
and as a result the first access to iomem space will fault.

Of course, this is a machine with CCIO, so it could be something going
wrong with the CCIO programming too.  But I think it's Dino.
