I've tried with the VidMode now and I suddenly remembered why it was not 
good: the virtual resolution. With VidMode resolution change when you 
move the mouse outside of the visible area the picture will also move 
(and sometimes the picture does not appear in the middle of the screen, 
because the visible area of the virtual screen is not the middle of 
it). The old kwintv had ugly hack to avoid this problem. XRANDR does it 
good, just that it has the ugly sideeffect that the window layouts are 
broken. :-(
