I know this week belongs to the Xbox 360, but sometimes you need a break from all of the hype. Once the Xbox Linux team got a mature system established they decided to move on to GameCube Linux. They’ve made a lot of progress:
The GameCube Linux kernel has working drivers for PAL and NTSC framebuffers, the Broadband Adapter (network card), audio, ARAM, Real Time Clock, gamepad, keyboard, DVD, MMC/SD cards (through the SD card adapter) and reset button. It has also preliminary support for memory cards.
Just last month they released instructions on how to build your own bootable disc.
