    Interesting - all my CF adapters (and I have several, some cheapo
    noname things to some branded ones) are dumb pieces of hardware -
    they merely convert the PCMCIA connector to a CF connector, just as
    dumb as those 240V mains adapters.

    Also, "CF" is just a different form factor of PCMCIA - don't get
    mislead by the term "Compact Flash" - you can get "CF" network
    cards, serial cards, bluetooth cards, etc as well. They're exactly
    the same as PCMCIA network, serial, bluetooth cards, just in a
    smaller package.

    If you have a CF adapter which behaves as you describe above, could
    you please check what happens as far as PCMCIA goes when you unplug
    the CF card - particularly what happens to cardctl status / cardctl
    ident ?
