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. Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
