Running a mainline kernel on a cellphone

Although I'm affiliated to Neo900 project, I'd like to keep the facts straight: it's the GTA04 project that works on kernel development and tries to keep it as close to upstream as possible. Then devices like Neo900, Pyra, lately also OpenPandora and BeagleBoard, and of course GTA04 itself (Letux devices) benefit from the work made on the GTA04 kernel :)
