I've fooled around with both the xorg.conf as well as the Display Settings. I changed the monitor hardware setting to an "LCD Panel 1440x900" but that didn't change much other than stretching my desktop icons. Setting it back to "LCD Panel 1024x768" un-uglifies my icons.

If you are running Fedora 11, and if you are running KDE, you have the option of using the display applet, which can be launched from the system settings applet, or launched from the command line like this:
$ kcmshell4 display
Once you are running this application, and assuming you have taken the unnecessary 'Modes "1440x900"' line out of your xorg.conf file, you should be able to test different resolutions using the applet, without having to log out and in after each change -- a big improvement over a few years ago.
As another poster has said, your display must support the resolution you are after.
