Thanks for trying. It does not work for me. I found that xfce4's control 
panel is able to switch between 1024x768, 800x600 and 640x480. (Xfce 
also resizes the virtual size.) I don't know how it can do it because 
theoretically the only valid modes are 1024x768 and 1280x1024.

If I remove "DefaultDepth 24" then Ctrl-Alt-Plus works fine and I'm able 
to switch from 1900x1440 to 640x480; but then the default mode becomes 
1900x1440 again :-(
