Excellent, this means that the two sub-devices are detected correctly.

This means the driver was not bound to the device yet, or the binding
failed.

We need to distinguish here:

pcmcia0.0 - ttyS0 got loaded without problems, AFAICS. Why do you want to
reassign the IRQ? You can do that by adding "exclude irq 3" to
/etc/pcmcia/config.opts, but I do not see why you'd want to do that.

pcmcia0.1 - ttyS1 did not start, because it couldn't find appropriate
ioports in the resource database. What's in /etc/pcmcia/config.opts? Try
adding

include port 0x4000-0x4fff

to that file, and run /sbin/pcmcia-socket-startup manually.
