SiS video on board (Score 1)

I'm installing RHL5.2 onto my friend's k6-2 333, which is a (aargh) HP product. The model number is the 6350, and it has some sort of SiS video on board, as well as sound. I'm trying to find the right video driver in the RHL driver list (this is the first time i'm installing Linux btw), but there's no SiS in there :(
Does anyone know where I can get this driver, or what it's called, and if its shipped with RHL5.2?
email me at [e-mail] if you can help me on this prob or RHL in general! need yer guys help! thanks alot!
