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?
I still maintain that either you need a modeline for 1600x1200 or the one you have is incorrect.
It looks to me that at the start of that log all common resolutions that don't have a modeline (or have a broken modeline) are rejected. It then starts the highest available resolution that does have a valid modeline.
