I thought somebody promised to add a pci_route_irq(dev) or some such so that the device didn't have to be enabled before the IRQ was correct.
I first reported this bad IRQ problem back in December of 2004. Has the new function been added?

Some rc.serial scripts extract IRQ and I/O port information from /proc/pci and stuff it into an unused port using setserial. That doesn't work reliably anymore because pci_enable_device() is never called, so the IRQ may not be enabled.
Thanks to Evan Clarke for reporting and helping debug this problem.
