Felix, to be honest with you, noone will fix this any more. Purely since there is nobody else but you around any more these days who still has any machine with an SiS chipset. So you can keep testing and reporting but it won't make any difference - nothing will be gained from it. The only option to get it fixed would be that you fix it yourself - but since you keep stressing you are not a developer this won't be an option as well.
