Hi, I'm the maintainer of gogo :-) The gogo 2.26a supports Athlon but you need a patched nasm (maybe you did it) or 3dnow tool by the gogo author.. I put the test version of port here: http://daemon.gnome.gr.jp/~nakai/gogo.tar.gz And please also send the authors about this report, because they are pleased the be faster (even it's little).
