laptop graphics problem with 9.2

In the two years I have had my Compaq 1500 laptop, I have at various times had Fedora Core 2 and SuSE (various, the last being 9.0) on it. I've never had problems with it until I tried to update to 9.2. Running sax2 brings up a white screen. I tried plugging in another lcd external monitor, and resolution on that one was 640X480, 16 colors. I had been routinely running 1280x1024, with 16 bit resolution. It has to be the driver, and in 9.0 I got good results using a generic LCD monitor. That no longer works.
