cgcc reported a duplicate initialisation. Mainstone includes a matrix keyboard where two different positions map to 'space'. QEMU uses the reversed mapping and does not map 'space' to two different matrix positions. Some other keys are either missing or might be mapped wrongly (cf. Linux kernel code). Don't fix these until someone can test them with real hardware, but add TODO comments.
