I'm covered by default on my other machine since it runs a diamondville Atom.

Why do you feel let down? A lot of the Atoms [maybe all, I haven't looked] are invulnerable.

Intel has just released some newer firmware for most of their affected processors, so maybe these aren't utter crap like the previous release that they had to pull back.
