Hi List,
Just loaded our favorite OS onto my new ASUS laptop.
Practically everything worked out of the box - I used the live DVD to 
check things out and installed from there.
I have followed
http://forum.notebookreview.com/asus-gaming-notebook-forum/553474-g73-asus-wmi-linux-driver-i-need-your-help-6.html
to get suspend working and also to get function keys working for LCD 
screen backlight controls working (Fn F5 and Fn F6).
Upon further searches I find that there is a kernel module asus-wmi.ko 
available in some distros that also allows some of the other Asus 
functions to operate - of particular interest is the keyboard backlight 
(Fn F3 and Fn F4) as well as the master backlight on/off key to function.

Question, does anyone know where and how to locate this (asus-wmi.ko) 
and get it functioning under CentOS 6.2?

I am prepared to set up the required build environment - but need some 
assistance as this is really at the limits of my experience. I have 
rebuilt the kernel to remove patches with some success previously and 
will have to dust off this knowledge if required.

TIA
