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.
