Thanks to ah-'s work, I was able to create a "book" that started the games,
but there is a big problem. If pygame is started while nickel is running,
pygame will wait forever until I press CTRL+C. The holdup is caused by
SDL (which pygame uses) calling the ioctl VT_WAITACTIVE. But if I start
pygame through a "book", I have no way to press CTRL+C, so the Touch
just freezes. You can read a few more details here.
