I would be inclined to guess that the ARM is just the CPU core
implemented in the same chip as all the other stuff the NXT uses.
One of the huge reasons for picking the ARM is that it's very well
suited to being integrated into the same chip as a bunch of other
stuff.

That much is very easy. The GNU C and C++ compilers have back-ends for
the ARM and there are LOTS of people doing all sorts of things on ARM
devices so there is plenty of expertise out there.
For example, there are people porting Linux onto the GameBoy Advance
and the Nintendo DS...so you just KNOW there is a ton of freebie stuff
out there for this CPU.
