Geez, and I thought trying to get my two monitors to work was  
difficult...  I eventually got fed up and gave up.  Better luck to you  
though.  The thing that bit me in the end was trying to use fullscreen  
apps.

I haven't a clue, really.  The Ubuntu docs are really well maintained,  
and they document the same software as your CentOS distro.  Perhaps  
these Ubuntu pages will help:

https://help.ubuntu.com/community/XineramaHowTo
https://help.ubuntu.com/community/BinaryDriverHowto/ATI

Just be wary with Xinerama, since it precludes desktop composition.   
Which is a pity, since it works better than TwinView, too.
