The 1280x1024 line is the highest resolution one that appears with that "Modeline" start, does that mean that it's the highest resolution that Xorg thinks is possible?
Quite possibly. In mine I remember seeing a section where it changed the specified horiz and vert sync frequencies to meet some specified recommendation CCE or something. Maybe it has doen something similar to yours which results in the change in max resolution.
