You can force the IRQ to 18 in the non-ACPI case via a tunable in the loader:

hw.pci4.0.INTA.irq=18

Odd, I only see dmesg's with ACPI enabled (which have IRQ 18), I've yet to 
find one with ACPI disabled.  Ah found it an earlier thread which has 17 for 
the !ACPI case.  So try it with ACPI disabled and the above tunable.  Also, 
it should work with both ACPI and APIC disabled.
