Once again, that message is just a warning, and Plan 9 should work fine in spite of it. On most systems, that is: occaisionally we run into a BIOS that doesn't set up the PCI interrupts correctly, and we try to compensate. We can only compensate if we know about the specific south bridge, though, and the warning merely means that we've encountered a `new' south bridge that we don't support. It does not necessarily mean that there is anything wrong with the interrupts as set up by the BIOS! I'll try to change the message to be less frightening... BTW, I recently made some changes in this area to work around a problem with the BIOS on some Sony VAIOs. The BIOS for these machines was setting the IRQ on one of the USB controllers to the wrong value. We now deal with this as well as the case where the BIOS leaves the interrupt line register in PCI config space as zero.
