The chances are that it is supported, just not recognised.
I don't know what chipset your card uses, but this will decide whether or not to use hostap etc (or you could just try the possibilities).
See what 'cardctl ident' produces, then see if this card description & MANFID combo is in /etc/pcmcia/config or /etc/pcmcia/hostal_cs.conf (I think all the files in this dir are searched to identify the card when it's plugged in - sorry, bit rust here, not had to do with for a long while).
If it's not, or if it's different, try adding it and see what happens.
If it works please add the info as a bug to the bug-tracker.
