There are several ways to get the kernel to handle IRQs differently.
Anyway, check PnPOS is disabled in the BIOS.

 cat /proc/interrupts

This will show what IRQs devices are using.  And check
/var/log/messages after inserting the card (with "tail -30", for
example, as root).  The file /var/log/boot.msg will give you clues to
IRQ assignments and routing that is happening durinb bootup, too.

If you have kernel-source installed, you'll find some useful
documentation such as
/usr/src/linux/Documentation/kernel-parameters.txt.  This contains
various boot options for ACPI and IRQs.  So does the Boot Prompt
Howto:

I can't give any specific information, just a few pointers, without
knowing more about your system and looking at the logs.
