Xfree 4.3 and SuSE 8.0, any risk ?

Hi ! I saw on the SuSE WebSite today that Xfree 4.3 is now available for SuSE 8.0. I read the README file and saw that it is at my own risk to upgrade my current XFree (4.2) As I am using Nvidia drivers to get a proper Graphical Acceleration System, I am not sure that the SuSE 8.0 drivers given by Nvidia will work after the upgrade. does anyone experience such upgrade on a SuSE 8.0 box equipped with Nvidia Card ?
