The generic PCI layer very well can turn off MSI on all devices when it starts up or a device is plugged in. That's all he is doing. Drivers essentially expect that the device comes up in INTX mode when the driver probes the device. All his change is doing is forcing that to be true, and there is no reason the generic PCI code can't do that.
