I don't think your problem is addressed by the recent discussion of TI
bridge interrupt routing issues.  Your problem is that your BIOS is
not assigning an interrupt number to the bridge.

As for what to do about it:

- see if your BIOS has options for directly manipulating PCI interrupt
  assignments.  Some do.  If not, see if you have a "PnP OS support"
  option.  If so, also try changing that.
- if this system is new enough to have ACPI support, then upgrade to a
  2.4.24 kernel with ACPI enabled, which may enable the kernel to
  figure out the interrupt routing for this device.
- if none of that helps, then post this to the linux-kernel mailing
  list, which would be most appropriate forum for what is really a PCI
  interrupt assignment issue, not a problem with the PCMCIA code.
