Some description is here:
http://en.wikipedia.org/wiki/Trusted_Execution_Technology .
And yes, I believe it avoids GPLv3: TXT allows user (I _hope_ it is
root-only) to boot tamper-free sandbox. As long as Windows (or
something) runs in the sandbox, I believe even GPLv3 would allow that.
OTOH... I do not think mainline kernel should support this. It does
not add anything to the user's security, and allows all kinds of nasty
DRMs.
