Just a suggestion, as I don't know if the there is a solution. Try the patch 
attached to https://bugs.freedesktop.org/show_bug.cgi?id=39949 to enable 
workaround for broken panning.

Then set Option "Panning" "800x600" and see what happens. Normally panning is 
for an area larger than the display, but maybe this or this in conjunction 
with xrandr can help.

Alternatively, maybe the LCD only provides 1024x768 natively, and by 
overriding EDID via xorg.conf to force 800x600 it may be possible to position 
its output into the usable area.

I don't know if laptops provide this, but standalone displays can be manually 
sized to dimensions smaller than full screen, which might allow adjustment to 
avoid need to use the damaged area.
