Suse 10 and my video card

Just installed Suse 10 from the cd and are finding my way in this great edition. I still work on 9.3 until everything works like I want to have it. Looking into the monitor and video card setup I discovered that in Suse 10 my videocard, a SIS 86C326 has a lot of choices in its setup. In 9.3 I have never found anything like that. Have no idea what they do and if i should alter them but can somebody enlighten me? E.g. what means the first choice MaxXFBMem and what values should this input show? Somewhere a place with reading material?
