The reason you dont get tutorials for newer boards is that the matrix was made very early, when there was only 1.0 and 1.1 boards around, i doubt the D0 point is in the same place for newer boards so the matrix wouldnt work. You might aswell get an X2.x chip for newer boards, they are cheap enough, or you could solder your matrix to the board, and i know for a fact there are these tutorials around.
