1365 x 768 Rsolution on A NEC Plasma display

Hello List: Has anyone every configured XFree86 to work with a display which can run at 1365 x 768 resolution? I guess I just need to edit my XFree86 config file to use this resolution, but how do I do that? I'm using a NEC PlasmaSync 50MP2 on SuSE 9.1 Pro, with an NVIDIA FX card (1.0-6106 driver). Thanks, Matthew
