I'm not sure this is at all related to the case we're talking about - it doesn't matter whether the request_irq or pci_enable_device comes first as the device is pulling on the interrupt line before the driver is even loaded. To fix that I'd think you'd need some kind of PCI quirk that would shut off the interrupt on the e100 card before any devices request the interrupt that it is sharing.
