Cardbus interrupt routing problem on Fujitsu Lifebook 520D

[Charles Briscoe-Smith <charles@briscoe-smith.org.uk>]

I have a Fujistu Lifebook 520D on which I've installed
kernel-image-2.4.18-586tsc and kernel-pcmcia-modules-2.4.18-586tsc.
I've had no problems using PCMCIA cards on this machine (except an Ambicom
WL-1100, but that's another problem), but when I insert a Cardbus card
(Net-Lynx "32bit 100/10M Cardbus PC Card", the only one I have as yet)
I get:

May 20 23:30:50 deuteronomy kernel: PCI: Enabling device 05:00.0 (0000 -> 0003)
May 20 23:30:50 deuteronomy kernel: PCI: No IRQ known for interrupt pin A of device 05:00.0. Please try using pci=biosirq.

I've tried pci=biosirq (for which, incidentally, I spent ages trying
to work out which of the pcmcia modules I was supposed to pass it to.
I finally found, by grepping the kernel sources, that it's a kernel
option...) with no effect other than to suppress the "Please try using
pci=biosirq" message.  I've tried pci=conf1 (no apparent effect) and
pci=conf2 ("PCI: System does not support PCI"), too, with no success.

Any ideas what else I should try?

Thanks,
