Hello!
While upgrading the hard drive on my notebook computer (and, by consequence, switching to more recent OS and kernel), I've "lost" one of my PCMCIA card -- it does not work anymore.
First, short description of my system:
hardware:
-- system: Fujitsu Lifebook 555TX (upgraded memory and hard drive);
-- ethernet controller 0: 3Com OfficeConnect 3CCSH 572BT LAN PC Card;
-- ethernet controller 1: Xircom Cardbus Ethernet CBE2-10/100BTX 32-bit;
-- BIOS allows to switch between PCIC-compatible and CardBus mode;
OS:
-- slackware-X.0;
kernel:
-- linux-2.4.26 (generic), linux-2.6.7 (generic).
3Com's LAN PC card still works. When I try to set up Xircom ethernet card, the error message is "SIOCSIFFLAGS: Device or resource busy" (I presume, because Texas Instruments PCI1130 and Xircom, both got "Interrupt: pin A routed to IRQ 0").
This combination (PCI1130 + Xircom) was working (2-3 years ago, Slackware-7.1 + standalone PCMCIA package).
I tried both 2.4.26 and 2.6.7 kernels (with and without pci=biosirq parameter) -- it does not work. Cardbus bridge always gets IRQ 0.
Here is some more information (BIOS in PCIC-compatible mode, Linux-2.6.7):

So, what could be done to fix this? What would be the path of least resistance here? Could this situation be fixed with setpci, kernel config or boot parameters, kernel patching or something else (without switching back to the standalone PCMCIA)?
Thank you in advance for any help or constructive suggestions,
