this is a common problem in game troubleshooting forums.

What you need to do is install the ati 9000 drivers. Your manufacturer will never update the drivers that came with your laptop. It is the same with the nvidia 2 go I have in mine.

So you manually install the 9000 drivers in control panel. Either through system drivers display, or display advanced adapter drivers. Uninstall and install from this location and click show all etc.

you will lose the power management features. Which are largely useless. When you are gaming you are plugged in most likely.
