That shouldn't have to be the case. : The IRQ will be shared between the bridge's isr and the cards though. It likely has to do with the fact that laptop mobo tend to be really cheap and it is easier to run one wire than two to the chip for the pci functions. I haven't looked at the code, but there are settings for the chip such that interrupts for function 0 go to INTA and those for function 1 go to INTB. However, if the mother board has these two wire or'd together it wouldn't matter...
