Detect whether the OXPCIE card is really present while in the ROM stage.
Use an int in CAR global data to store whether or not the OXPCIE serial card
is actually there. Also, time out if the card doesn't show up quickly enough,
don't continue initialization if it's not there, and don't make the
initialization routine default to a card if none is found.
