One of solution is displaying on your VGA whole 1400x1050 scaled to
1024x768 (picture will be little "weird" but you will see everything
at least). I use this to display 1920x1080 on both: my TV (1920x1080)
and LCD (1600x900). However I don't know how to add such a mode to
xrandr manually. It's just available for me out of box (xrandr
--output PANEL --mode 1920x1080Scaled).

If I get idea of Randr 1.3 and padding right, this will be other
solution when we will get Xorg server 1.6 released.
