Patch is in two parts: dino bit just corrects some thinkos in the card
mode dino code and adds the actual dino device to the prints (useful for
debugging if you have more than one dino).
The tulip fix simply adds the card to the tulip card table and makes it
all work.
I've tested this on my C360...however, I had to hack the ccio window to
get that to work...I need more time to make this code better.
