I got that to work on my 14" T61p (1400x1050) by:
- adding the line
       option "CustomEDID" "DFP-0:/etc/X11/t61p-edid-augmented.bin"
  to my /etc/X11/xorg.conf in the "Device" section
- and by putting the attached file into the specified location

I found a tip on how to do that on some ubuntu web page, if I remember 
correctly. This custom EDID file adds the 1024x768 mode to the list of 
supported modes.

Regards,
Martin
