Maybe I don't get the point, but IMHO: when the card needs to be mapped at
a special address in order to work, this should be stated in the CIS entry.
If this is not in the CIS, the CIS is broken and the card should get a
quirk entry.

Any default will fail for someone. IIRC the move to 0x400 has been done to
find enough free space for things like wavelan cards, that map (relatively)
huge continous io ranges, thus failing in typical PC configurations when
inserted into a pcmcia slot mapped below 0x400.
