Problem with screen resolution after installing F12

[Dick Roark]

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.

Here is my xorg.conf file:
