    OpenBSD solved this problem by listing this card in
    pcmica_cis_quirk.c. Maybe you can try that as an iterrum solution?
    That's the short term solution. I really hate the quirks in the
    present system and plan on doing something about it.

    : I.e. something akin to:
    :
    : #cat SW_775_SER.dat > /dev/pccard0.cis
    :
    : Looking for a solution on either 5, 6 or CURRENT.
    :
    : Any hints - or guidance how to best map this into the quirk section - as
    : the fields are not quite clear to me.

    We just got the ability to dump the CIS out of a card. It is unclear
    how we should go about replacing the CIS in the kernel. Do we do this
    by loading the CIS in before the card is inserted? Do we keep a
    database of bad cards and automatically subsitute the right one? Do
    we detach an reprobe the card when a new CIS is loaded in (like your
    example above)?

    Being able to load CIS in would fix a bunch of multi-function cards
    that aren't listed as such (and vice versa).
