ATI Catalyst™ 9.11 Driver on CentOS 5.4

Tried to install ATI Catalyst™ 9.11 Driver on CentOS 5.4 with the Integrated ATI Radeon HD 4200 graphics in the motherboard GA-MA785GT-UD3H (rev. 1.0).

1st try failed.
looking at the error log at
/usr/share/ati/fglrx-install.log

Turns out that I need to install the kernel headers before I install this driver.
installed the header rpm for 2.6.18-164.6.1.el5-x86_64
and it works fine now.
Yet to benchmark it though.
will try this soon
