Okay, this looks good. You are using the correct framebuffer driver (the ATI Radeon driver and not the OpenFirmware FB driver, which won't work for X) and it appears that your monitor is correctly responding with an EDID for autodetection. Can you try generating an X config file with xac and give that a try? If it doesn't work out of the box, try uncommenting the "UseFBDev" option and try both "true" and "false", sometimes the correct value is not autodetected by X. -Joe
