It's good to know you have tried.

It's possible. For the interrupt, see /proc/interrupts and "lspci -v".
As for the motherboard, it's possible too. First of all, please try to
use a clear port area, such as 0x0c00-0x0cff, in /etc/pcmcia/config.opts.
Please note that posts between 0x100 and 0x3ff modulo 0x400 are less safe
than the 0x00-0xff range modulo 0x400. Don't even think of using the
0x100-0x3ff range - it's a minefield :-)
Enable PNPBIOS either in the kernel or in pcmcia-cs and use lspnp utility
from pcmcia-cs to see if any the ports overlap with ports in /proc/ioport
(use "lspnp -v"). Unfortunately, the kernel doesn't reserve all PNPBIOS
resources automatically yet.
See if your motherboard is missing in drivers/pci/quirks.c in the Linux
kernel while similar IDs are present for some quirks.
I would not exclude hardware problems too. If you can, try another PCMCIA
card in the adapter and your PCMCIA card in another adapter.
