With SandyBridge, Intel has changed these Socket PCI devices to have a class type of "System Peripheral" & "Performance counter", rather than "HostBridge". So instead of using a "special" case to detect which devices will not be doing DMA, use the fact that a device that is not associated with an IOMMU, will not need an identity map.
