Also I think THINK that actually the video card is recognised and works after the system finishes loading. I did try running a game and it seemed to work. How can I check if it's running with up to date drivers?
THAT being said, you're most likely using the proper card because it did load the module. What game did you launch and would it have laughed at the integrated card?
If the GUI is up and seems to be just not doing a lot, hit Escape and see if there is a message about "refreshing hardware" or something. I forget the actual lingo
