The DSLinux project has ported the Linux operating system to the Nintendo DS and Nintendo DS Lite. Newer models such as DSi and 3DS might work in DS-compatibility mode. Apart from real hardware, DSLinux also runs on some NDS emulators, like desmume.
DSLinux is functional, has excellent documentation, and brings a wealth of useful Linux programs to the DS.
