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

: 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).
