Privacy, Security, Encryption When was the last time you reverse-engineered all the PCI devices on your motherboard?. . . Enters the game-changer: IOMMU (known as VT-d on Intel). With proper OS/VMM design, this technology can address the very problem of most of the hardware backdoors. A good example of a practical system that allows for that is Xen 3.3, which supports VT-d and allows you to move drivers into a separate, unprivileged driver domain(s). This way each PCI device can be limited to DMA only to the memory region occupied by its own driver.

Your best bet to get a laptop using CoreBoot to avoid the BIOS backdoors would be with begging the Linux only laptop companies like Zareason and System76. They would be the most likely to actually build specifically for maximum compatibility.
