Ahh, no.
A SMP kernel (or one with UP IO-APIC) is not going to be helpful for this, actually. SMP will take the irq data from the MP block, not the pirq table (that can be considered something of a misfeature right now, but getting the mixture of PCI irq redirection from the MP tables and the pirq irq routing information right together is probably not worth it - especially as I don't think any MS OS has ever done that either, so the BIOS writers have never experienced that combination - so it's almost guaranteed to result in strange results).
