Lost Newbie......

Sorry if this sounds redundant…
I am so lost on how to install my OpenGL drivers. I have SuSE 7.1, a Viper V770 Ultra, and have downloaded all the apropriate drivers in RPM format. If I try to run the rpm in X it says there is a dependancy prob with mesasoft 3-7 something, so if I exit to console mode nothing changes. So how do I restart my computer to a different run level so that X doesnt start and mesa isnt loaded, also how do i install, I have read the Fing manual and nothing is getting through my thick skull, thank you so much for whatever little help you can offer.
