It would be better for for a non-invasive match (aka `probe') function to
simply verify the existence of the card.  Remember that a card that is
matched may not be attached, necessarily.

If there is common code to nail down the location of the shared memory in
I/O or memory space, put that into a separate function and use that in
both the match and attach functions.

I don't have any comments on this, sorry.
