Just because the card is recognized by the OS as installed hardware, doesn't mean that a driver has been loaded for it. What is the output of the command "lsmod"? In any case, most modern cards support the vesa driver specs, so you should be able to specify vesa as your hardware driver when you install Ubuntu, or run the X configuration tool. It will only provide a maximum of 1600x1200 resolution, and performance is not adequate for full-screen, full-motion video, but for most stuff it works ok.
