I had missed a line of code to either add or subtract 0x10 to move 1 rank.
If you want to do this in a color-independent way without any ifs, you can XOR the rank with 0x10. With normal 0x88 numbering this maps 4th rank into 3rd (and vice versa), as well as 5th rank into 6th.

Quick Perft (7) takes only 8.9 sec on my new Core 2 Duo machine (E6600, 2.4GHz)! Cool
