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.

It's definitely a concern

Hardware security from backdoors has been a concern of mine for some time because if you travel to China (as every businessperson learns) you will find that your items are not secure. Many business travellers find malware planted on their machines and foreign companies often have very strict policies employees must follow to avoid loss of IP.

I'd like to buy a Lenovo laptop running Linux sometime but given this background....

Thanks for the link because my guess is there might come a time when suddenly everyone gets very interested in this topic.
