Video Configuration on RedHat 7.2

I have a laptop, ThinkPad T23. I am dual booting it with WinXp and RedHat 7.2. The installation of Linux went fine except for detecting the video drivers and the display type. I can’t startx, it keeps giving me display type error messages. The video on the laptop is S3 Super Savage IXC16 with a 14.1″ TFT SXGA 1400×1050 LCD resolution.
Did anyone get the GUI to work an such model?
Please, I need help!
