Personally, I prefer the ati-x11-drv from freshrpms along the dkms package from FC6 extras but that is besides the point*.
Your /etc/X11/xorg.conf file looks similar to mine (included for comparison), please check and see if you have the imlib rpm packages installed; rpm -qa 'imlib*'
Expected output for example;
$ rpm -qa 'imlib*'
imlib2-1.3.0-3.fc6
imlib-1.9.15-2.fc6
* I like the idea that when a new kernel is installed or upgraded I do not need to download and install new packages from linva, the ati-x11-drv automatically gets rebuilt for the new kernel at boot-time.
And before I forget my xorg.conf file;
