Thanks a lot for clearing this up.
It's sweet to see Open Freespace in all it's glory under Linux.
The only problem I have now is the joystick which is from Microsoft.
Maybe they can't make OSs properly but that joystick is nice, it was the first forcefeedback joystick available and it still works at least technically.
But my kernel gives me an error when I modprobe sidewinder.
But I know this is not freespace related so I shouldn't rant about it here though I am open for suggestions

Is there any good joystick that works properly in Linux? What about forcefeedback?
