I personally use the Vantec Lapcool 2. I have the M40 which is also a 15.4 widescreen. The cooler is actually too small, but the laptop body just sits on its feet without a problem.
I posted pics a while back.......
Actually, I previously owned that model, and once you upgrade to 1 GIG or more, the amount of memory shared with the video card is automatically set to 128 MB. In fact, you cannot even set it to anything lower then 128 MB through the GUI.
Did you try uninstalling?
Control Panel -> Add or Remove Programs
Alternatively you could disable it from running at startup.
Start-> Run -> Type 'msconfig' (without single quotes) -> click the startup tab -> now...
