I probably will allow the whole CAM support to be completely disabled, but
first I want to get it _working_.

Well, just take a look into the driver and you'll see why this happens.
The driver _always_ says that there are two slots, it doesn't check whether
there actually _is_ a CAM adapter present (I don't know if that would be at
all possible).

Sute, that's a minor cleanup thing. Yesterday I was pretty busy hacking around
to get at least _something_ to work, so I really didn't care much about such
things.
