Summarized for the cynical among you:

"If you hijack the SMM code, and then use a blowtorch, you can hijack
the Pentium".

If you can use a blowtorch, you got physical access and it's game over anyhow.

If you can scribble on the SMM code, you 0wn the box already.

I'm not at all sure what the point is here, unless they've found a new way
to get into the SMM code and then force a *spurious* SMM trap *without* already
r00ting the machine....
