Comment 7 for bug 444235

Actually this is already fixed in linux kernel.
This address space collision is only a message.
You see, kernel finds that BIOS AML is accessing the same resources
and thus automatically disallowing the driver (i2c_piix4) to load.

Of cource if you blacklist this driver, kernel will not find space collision and thus the message is not shown during boot.
But the result is the same: the driver i2c_piix4 is not loaded anyway.
