I don't know what the "Kogge-Stone" algorithm is. ;-/ I haven't had a chance to use Altivec for chess yet. Although I have been playing with some ideas. Mostly I have done DSP code; signal analysis, transformation FFT, digital filters and different modulation types PSK, QAM, AM, FM and analysis for hopped signals. Altivec was fun because it made me think about some of the algorithms in a different way and it turned out to be a better way of doing things. In the game department I did a game of life (several different versions of it), which turned out to be extremely fast and then combined it with openGL. Also some Cellular Automata algorithms, but I have no comparison for those since I never implemented them in any other way.
