[CentOS-docs] guidelines ATI Display Cards on wiki pages

Ralph ,

Can you add guidelines on the Newer ATI Display Cards wiki page 
regarding the Mesa problem .
after installing the ATI driver from ATI web site and doing everything 
on the wiki
i get Mesa driver when checking the driver with "fglrxinfo" .
to solve this problem what i did was :
1. Before installing i deleted the Mesa libGL files :

rpm -ql xorg-x11-Mesa-libGL-6.8.2-1.EL.13.37.5

/usr/X11R6/lib/libGL.so.1

/usr/X11R6/lib/libGL.so.1.2

/usr/lib/libGL.so.1


2. Then install the ATI driver .
 
This way the driver will make its own libGL.so files with the 
appropriate symbolic links
