The exploit talks about modifying SMRAM. It's done with root level access on the computer. And in my understanding, the effect is not permanent, since you're changing RAM. Reboot, and it'll be gone.
Really?? As I understand RAM memory dynamic RAM works as you describe but not static RAM. Which is SMIRAM?
