Interesting choice of words; "jailbreaking" is something the user does to advantageously overcome limitations placed on a device by its manufacturer. What does jailbreaking my CPU allow me to do? Turn it into a brick if I'm not careful. Potentially turn it into a different CPU? (Shades of Crusoe.) Change its identification numbers?

Yeoch, another security vulnerability to worry about. Apparently a bios update has already been released you can install to fix it.

Cool! I'd love to see what custom microcode comes of this. Especially in relation to the speculated backdoors on CPUs
