I spent several days trying to figure out how to configure my sunblade 150's xorg.conf file. I'm posting my xorg.conf to make it easier for anyone else trying to do the same. It displays a resolution up to 800x600. The most important part is the reference clock option in the device section set to 29.5 Mhz. You can mess around with the modes to try to get 1024x768.
