I used:
hw.acpi.pci.link.0.11.0.irq=9
hw.acpi.pci.link.0.11.1.irq=9

In /boot/loader.conf, and I get a panic right at boot...  If I unset 
them using loader, system boots fine.  I also tried using irq 20, same 
thing.

I don't know what this statement means... I tried looking for more 
documentation about it.

Is this a function of the BIOS, or the O/S?  If its in FreeBSD, where 
can I find more information about this?
