Either I am not sure this fixup is necessary, though IIRC it did solve some problems. Since this latest round of Via fixups, I would like to remove that little change in via audio, and see it anyone complains. The 686A and 686B docs list no irq after 14. Adrian Cox has said that setting the PCI intr line value actually makes a connection on the PIC, instead of just being a scratchpad register like it is normally. Adrian said the same thing about the USB IRQ, and I presume the other internal irqs (like ACPI) listed for register 0x58 apply as well. -- Jeff Garzik | Disbelief, that's why you fail.
