If there were 2 systemace devices on board; one attached to a CF slot
labeled "1" and the other to one labeled "2".  :-)  Same problem as
lining up serial device files to physical port numbers.

The driver doesn't technically need it, but the information does need
to flow through to the creation of logically numbered device files.
