Yes, actually of the 6 cards I have, all are seen except the USB card. 
And the USB card is seen in all other slots. So it appears to be a SLOT
issue, but not a card issue.  Somehow this card is unique and uncovering an
error that I don't know about yet. Perhaps I have a single address line
sizzled or something. This is the same slot that has the IO resource
allocation problems; I don't think I need to debug that in Linux. 

OR.. 

Is there any PCI test code out there??? Maybe I should forego the drivers,
and figure out some kind of test. I made a blind assumption in U-boot that
if it worked to detect cards that everything was in order.
