I am not sure if the above option should be on the kernel command line
or in the /etc/modules.conf, depending on whether the option is for the
PCMCIA *module* or for the Cardbus interface that is compiled into the
kernel.

It seems to me that Linux is seeing the card bays

Probably the same problem as above.

The second card bay.

I must compliment you for providing very good information about the system
in your post. Let us know if adding the pci=biosirq helps. Otherwise this
system is so old that it is hard to remember technical details applicable.
