I have just installed OpenSuSE 11.0, but I am facing an issue with my VGS, the OS is recognizing it as an S3 card while its ATI !!!

I dont remember the VGA model, so I c hosed the 1 click install to install the ATI driver which is general for all radeon cards, its installed successfully but the system is still running the S3 driver
