Configure x11

I am still working on getting my formac proformance 3 to work. Now I have done a clean install using the 8 CD box of SuSE 7.3 that arrived today by mail. For the first time Yast2 worked for me and I have proof that there must be a way to enable a graphical interface using this card. I tried configuring the X-Window system using sax2 and xfree86 but nothing worked. I always get an error message saying: Fatal server errors: no screens found But I am sure that it has to work somehow. Can somebody maybe point me in the right direction? I don't think I will have to re-compile the kernel with a specific patch since yast2 worked flawlessly... Any help is greatly appreciated. Stephan
