I assume you mean 1400x1050 .

There's a workaround that I hacked up to fix this on my laptop.  Use the 
packages in the repo at http://pjones.fedorapeople.org/xorg-x11-drv-ati/ 
, and add the following to the "Device" sections of your 
/etc/X11/xorg.conf :

         Option "LocalTextures" "off"

You may also need to add:

        Option "GARTSize" "64"

or

        Option "GARTSize" "128"

This should get you going for now, but the change isn't what's going to 
be the final fix in upstream Xorg, so you'll probably want to add 
"Exclude: xorg-x11-drv-ati" to your yum configuration until the real fix 
is ready.
