im also a newbie in linux, and i started with the same version as you around 3 week ago, i got the same problem, with the same graphic card lol, that's weird....
To answer to your question , do this:
-login as root on console
-type "YaST" ( capital letters are important)
-if YaST doesnt work, type "Sax2" or "Sax"
-With the command listed below, YaST will appear ( graphically, just as in linux )
-go set up the graphic option
-save then exit
-then before reboot type "startx"
-linux suSE 9.1 should run
-Reboot and all will be setted up
I hope that ull resolve ure problem, coz i got the same one and i wasnt really happy
