Problem with screen resolution after installing F12

After installing Fedora 12 I am having problems setting up 1280x1024 screen resolution.  Only 640x480 and 800x600 are available. I was using F11 at 1280x1024 on this hardware before upgrading to F12.  After that, so far no joy.  I would appreciate any helpful info.  I have also tried using various configurations of the xorg.conf and xrandr without success.   Obviously, I'm missing something.  I feel certain that the fix is right under my nose but so far, nothing works.
