I don't think wether fixing or not SDL is the debate here, the question would be more wether or not we want to add a lightweight display driver to qemu. Also, I think a DirectFB driver is fairly easy to maintain. I will get some performance data as soon as I have some time. By the way, sorry for the patch reposts, it seems that my smtp server had quite some trouble to relay messages last week. -- Julian
