We plan to release an early version of it sometime soon after 6.1 gets released. Right now, the hack is very basic and underdeveloped, and there is a lot of room for user error to screw up the board. Besides the legal issues, that is the main reason why we disabled so much stuff on the test board... There's just too much room to screw things up right now. And of course there's the not-cache-friendly thing, which we're gonna try to work on.
There are several other nifty features that we want to implement into the hack eventually (and that we won't tell you about quite yet), but for right now we're just concentrating on finalizing the main portion of the hack and waiting for 6.1.
