Actually, I am using the CVS code, but I haven't done an update in about a 
week :)

I found *my* problem. I was not initializing the joystick subsystem of SDL. I 
still think it should be able to handle that without segfaulting, but since 
it's technically "undefined behavior" I can't complain :)

It should, however, probably be noted in the SDL_JoystickOpen() and 
SDL_NumJoysticks() calls that they will not function correctly unless the 
joystick subsection was initialized in the call to SDL_Init(). I wasn't aware 
that the joystick parts needed explicit initialization, since it wasn't 
referenced.

I was able to get everything working nicely, although I found that Mandrake 
8.0 didn't correctly set up the joystick driver - it needed a little manual 
intervention.
