I'm not refering to some virtual screen implemented by the window
manager.  I'm talking about virtual screens implemented by the X-Server:
You can put multiple mode lines into your XF86Config file, for example
"640x480" and "1024x748".  That will give you a 1024x740 sized screen.
You can and then switch between "640x480" and "1024x748" with Ctrl + Alt
+ plus/minus (or via VidMode extention).  If you are running with
"640x480" the X-Server will pan the display if needed.

What will happen if I switch to fullscreen mode in 640x480 ?

Ok.  Looks like setting _NET_WM_STATE_FULLSCREEN should be enougth ...
