Are the drivers being loaded? This done by cardmgr, and it uses the
/etc/pcmcia/ scripts (network.options, memory.options). If you got a
consistent response from cardctl for

#cardctl ident

Or something like that, your pcmcia interface should be working.

Remember that pcmcia drivers should be loaded by cardmgr, not by a simple
insmod. This is because the driver waits for a CARD_INSERT event, which's
generated by cardmgr.
