I have reslove the problem,in the kernel2.6.10,the ths8200 driver started before davincifb driver,so the davincifb get the right mod_info ( xres(800) ,yres(600)),but in the kernel2.6.18,ths8200 driver boot after the davincifb , so the davincifb get the default mod_info and set its values.change the davincifb_probe() can resolve it!
