--- Comment #44 from Terry <seahcw at sg.ibm.com> ---
We have updated the EDID of the machine and xrandr now shows 800x600 support. 
This is tested on SLE11 SP3 kotd version 3.0.68-31-pae and 3.0.70-33-pae. Here
is the output of xrandr:

hwinfo --monitor now also shows the monitor's support for 800x600
