I don't know about other parts of the world, but in the US, contrary to popular belief, kits that are almost entirely assembled (just plug in a few things and stick them in a case) are most definitely NOT exempt from FCC part 15 requirements:

You could run the clock really slowly to avoid this problem in the US, at least. Battery powered devices where the maximum clock speed is under 1.705Mhz don't require FCC certification. You'd be able to deliver a usable (if slow) calculator at that speed and if individuals hacked it to a higher frequency that's their problem. Of course you'd need to somehow recognize that possibility and make hacking it "hard to do". (See question 3 here.)
