Well, it does seem to work. This is another area I've only looked at a 
bit, to fix IRQ setup in Plan 9 and such. 

I've been looking at the Linux arch/i386/kernel/pci-irq.c file and it
seems to be able to manage using PIRQ tables to set up IRQs, even handling
the weirdnesses of some chipsets. Have you checked this out? It's 
educational. This is the file I was hoping to start with for IRQ 
assignment in linuxbios. If there is a problem with my idea let me know.

Eric I don't get your comment about the "kernel PCI code not assigning
IRQs" in light of all the kernel code that does this. I think I 
misunderstood you, can you explain.

thanks
