The SDL output also gets fullscreen right when xmga doesn't. Sometimes 
pushign the fullscreen button followed by modeswitch button works, 
sometimes you have to push fullscreen too to not just have a movie size 
of 1024x768 viewed through the 640x480 you just switched to. I can't 
remember the details of the behaviour, but in the end, SDL seems to get 
it right, right away with minimal fuss and tinkering.
