Bug in pcmcia-core

I have tried conacting the mailing list for the PCMCIA subsystem in Linux, but no-one seems to respond.

I am trying to write a Linux ALSA driver for the Creative Audigy 2 NX Notebook PCMCIA card.
This is a cardbus card, that uses ioports.
When it is inserted into the laptop, the entry appears in "lspci -vv " showing ioports used by the card.
As soon as my driver uses "outb()" to anything in the address range shown in "lspci -vv" , the PC hangs.

I can only conclude from this that ioport resources are not being allocated correctly to the PCMCIA card.

Can anybody help me track this down. If someone could tell me which PCMCIA and PCI registers should be set for it to work, I could then find out which pcmcia registers have not been set correctly, and fix the bug.

It seems that the PCMCIA specification is not open and free, so I cannot refer to it in order to fix this myself.

Can anybody help me?
