>A number of Intel processors since the introduction of the Nehalem microarchitecture (that is, a number of CPU branded Core i5, Core i7, or later) support VT-d, an IOMMU implementation. This allows the operating system (OS) to isolate a device in its own virtual memory address space (in a manner analogous to the isolation of processes from one another using the MMU). Devices could thus be prevented from having access to unauthorized parts of the memory space. However, this feature isn't generally used other than for its initial purpose of giving guest virtual machines passthrough access to specific host hardware.[citation needed]
So.. maybe? Resolving that 'citation needed' would be nice.
