If you look at the drvXy566.c file you'll see that ai and wf support
effectively use two separate drivers, and I think they use different
base addresses for their cards.

Try executing "xy566_io_report 1" instead, and you may see something
different (like no cards present maybe).  I've never tried to use wf
records with the 566, so that's about all I can contribute, but it
should get you started.
