I think the joystick driver only reports axii, so SDL has to use an
alternate method of determining which axii are really hats, and such.  In
this case, you would want to use the SDL_LINUX_JOYSTICK env. var to
properly configure SDL:

For example, I use:
export SDL_LINUX_JOYSTICK="'Logitech Inc. WingMan Extreme Digital 3D' 4 1 0"
