The fixup code that handles the case for PowerMac's that leave bridge
windows open over an inaccessible region should only be applied to
memory resources (IORESOURCE_MEM). If not we can get it trying to fixup
IORESOURCE_IO on some systems since the other conditions that are used to
detect the case can easily match for IORESOURCE_IO.
