Where is it "set up" to use IRQ 9? Does this match the IRQ that the
'pcic' driver claims it's using?

There's an arbitrary limit on the length of the string, I believe. The
error message you get here:
> Mar 9 14:11:55 mediateket pccardd[228]: No card in database for "MICROCOM, Inc.

means that it didn't find the device in /etc/pccard.conf.

This indicates that either all the 'sio' drivers in your kernel are
already committed to devices, or the probe failed.

They may be related insofar as the 'sio' driver typically expects
serial ports to behave like "real" UARTs, and the current crop of
devices includes many that fall far short of this. 8(

You need a free sio device; you can arrange this by configuring eg.
sio2 and marking it disabled.

It's generally not a good idea to try to reuse any resources, even if
you're not using any device(s) attached to them. Apart from this and
the possible IRQ curiosity above, I think you're very close to having
it all correct and working...
