Building X.Org from source

I have a laptop with an S3 Twister-K graphics chip and Im want to enable its OpenGL support under SuSE 9.2. I have found a page (http://dri.freedesktop.org/wiki/Building) which has instructions for doing just that, but it involves compiling a new version of X.Org, MESA and DRM. I don't think that I can do any of this via RPM, so I was wondering what issues I might have with YAST once I'm finished. Paul
