Thanks for your advice .

 I refered to the ATI driver installation doc and found the following
message :

Note: If a Linux 2.6.11 or newer kernel was built with
CONFIG_AGP enabled, the kernel AGP frontend is required to load
the fglrx kernel module. To identify whether your kernel was built
with CONFIG_AGP enabled, look for CONFIG_AGP=y in the
kernel config file, or if the 'agpgart' module is loaded.

And I found  that module is not in CentOS 5.5 x8_64 .

So could I compile the kernel that enable that module ?

Isn't  it right ?  Thanks ...
