First "proper" Mac OS X for Intel torrent leaked?

Not sure what became of the torrent leaked a couple of weeks ago that had folks speculating that Apple was intentionally seeding copies of OS X for Intel into the wild (though signs were pointing to fake), but there's now supposedly a legitimate build that's been leaked, as "borrowed" from a test developer box at WWDC '05. Folks are reporting that they've gotten it to work by modifying the incorrect instructions from the leaker — if you wanna live on the bleeding edge, there's an install guide available.
