Does your X86Config-4 file contain a modeline for 1280x1024? The xserver contains some internal modelines for "normal resolutions" but requires you add a modeline for others. I had the same problem trying to get 1152x864. You might try xvidtune to generate a modeline, I am sure there are other tools available, or if you have a copy of an XF86config file for XFree86 version 3 which had worked for your video card and monitor you can copy this to your XF86Config-4 file, below is where I placed my modeline in my XF86Config-4 file.
