The ARM7 is in the GameBoy - but the ARM7 that's in the Nintendo DS
is only used for running GameBoy games. It uses the more powerful
ARM9 for native games.
But there is already a Linux port to the ARM7 - if the NXT has

to finagle the USB port to be a master instead of a slave - then
you could run a full blown operating system on the NXT.
