The first test of SuperTux Live! v0.92.1, aka "AYBABTU Edition", was a minor disappointment. Since Myah's built-in xorg.conf didn't work, I cobbled together my own version and it still didn't work because I misnamed some of the input devices. (This is big- if xorg.conf doesn't work, X doesn't work, which means graphics don't work.) In addition, I forgot to link together some libraries. But those flaws are fixed, and I'm regenerating the image. It should work fine now.
On a related note, I'm looking into the possibility of having a Crux-based system... ;) Never mind.
