IRQ? problem or am I looking in the wrong area?

I have a PCI wireless card and when it's inserted will not show it's interrupt in /proc/interrupts

cheking the /var/log/messages turns up

No IRQ known for interrupt pin A of device 00:00.1.

I've googled on this and made two recommended changes.

Edited the grub.conf now reads

kernel /vmlinuz-2.4.18-14 ro root=LABEL=/ pci=biosirq

(I added the pci=biosirq)

and set a bios setting to Plug -n- Pray OS = no

I still have no luck...

More info:

]# /proc/pci
lists the PCI device with IRQ9

it's not in /proc/interrupts

]# lspci -vvx
also finds the device

Below is the end result

[root@localhost root]# modprobe prism2_pci
/lib/modules/2.4.18-14/net/prism2_pci.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
/lib/modules/2.4.18-14/net/prism2_pci.o: insmod /lib/modules/2.4.18-14/net/prism2_pci.o failed
/lib/modules/2.4.18-14/net/prism2_pci.o: insmod prism2_pci failed

if it's a pci card it should be automatically detected, no fiddling around with irqs needed.

what model of card does lspci show?
