That error message suggests that the driver doesn't support dual head operation. Looking through the Intel driver changelog, dual-head support wasn't added to that driver until mid 2004. The XFree86 version you are using dates back to mid 2003. You should upgrade your X-server to something at least a couple years newer. Mark.
