Linux on Game Cube is reality, finally.
The Game Cube gaming-console by Nintendo comes with a 486 Mhz PowerPC CPU, ATI graphics, 40 Megs of RAM and, optionally, with a 10/100 ethernet card. Finally all the efforts made were succesfull in booting linux kernel on the Game Cube.
The kernel already has support for several devices, like sound, monitor output and keyboard too. A telnet server and a web-server were embedded, so you can easily understand that networking is working too.

GameCube is powerful enough to run many cpu intensive tasks, such as divx playing. Anyway, as you know, GC does not ship with an hard disk, so everyhting should be loaded remotely. And Linux can be used to turn your gaming console into a thin client, a diskless terminal (without considering embedded applications).
