[Gllug] Microcode update

1. If you're able to update the microcode, then you already have root
   anyway, and hence can do any damage you like.
2. The microcode changes are volatile (i.e., they don't survive a power
   cycle). Admittedly, that doesn't affect those of us that leave our
   machines on permanently, though :-)

In principle, though, it should be possible to write a microcode virus,
but you don't have much in the way of tools to work with.
