Sorry, I think you misunderstood. I've certainly seen my share of crazy devices doing things like endian-reversing the MSI address and sending interrupt messages off into random space. The only thing I was disagreeing with was that Jeff suggested it was a driver bug not to do pci_intx(0) when enabling MSI.
I don't doubt that there are broken devices out there that do generate wire interrupts even when MSI is enabled. I just don't think we should go around "fixing" working, correct drivers for devices that _do_ follow the spec.
