OK...Just to confirm what you're getting yourself into:

The yenta socket is a deep black art.  It also covers a multitude of
slightly different standards (from different manufacturers).  I learned
enough of the sourcery to say the required incantations for my
particular needs (which were a B180 with a PCI<->cardbus yenta socket
that came free with my zoom wireless card).

In order to get my setup to work, I also had to replumb virtually the
whole of the dino PCI system (I needed this because the B180 firmware
barfed at the PCMCIA socket and simply disabled it).

The point, I'm afraid, is that although I got it work for me, I'll bet
not much of the magic is transferrable, so you may also find yourself
ploughing through the yenta specs...

If this hasn't deterred you, then read on intrepid adventurer.

One of the things you seem to have from the error messages is IRQ
misrouting.  Could you boot up (or stop PCMCIA, remove all the modules,
including the core and restart) with a card in the socket?  The socket
status should tell us which one, and the IRQ line is given by lspci. 
Since the chip is both PCI device functions, it's not impossible to have
the IRQ routings messed up.
