Summary: IRQ conflict- how do I set/reassign IRQ number?

Initial Comment:
Problem getting D-Link DWL-520+ PCI card running under
RedHat 9.

I suspect that the problem is an IRQ conflict. How do I
re-assign the IRQ number for the card?

Here is why I suspect an IRQ conflict. The driver
builds just fine, but insmod cannot mount it. I get:

./../src/acx100_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

When I check dmesg, I find:
  PCI: Found IRQ 11 for device 00:09.0
  PCI: Sharing IRQ 11 with 00:10.1
  ymfpci: YMF724 at 0xec010000 IRQ 11

I believe YMF724 is my soundcard (a yamaha)

The card works (more or less) under windows 2000, so
apparently motherboard supports PCI 2.2.

Thanks for any ideas,

Hmm, strange.
I cannot see here why it chooses to fail...

Please resubmit a log with debug=0xffff.

Thanks!
