Yes, they are supported. Scroll down the 'read me' file and you will see witch Mobility chips are supported. I just installed the latest Beta on my Asus as I have done with each of the previous ones...using the link below. You MUST install the existing drivers and reboot before attempting to install the new beta.
EDIT: This is assuming you have read "Updating Mobility Drivers" and don't have one of the listed manufacturers product or 'switchable graphics'.
