Help with screen artifacts after MB upgrade.



My MB died due to a flaky power supply fan. I ordered a new MB and CPU from E-Bay. I was expecting an identical MB to what I had (which would mean no driver changes). Unfortunatly, the CPU which was advertised does not actually run on the old PC-CHIPS board that I had. The seller provided me with the advertised CPU on a newer board that does support it. I now get occaisional artifacts remaining on screen when windows are moved around. Not always, just every now and then. I am guessing that I need to change something in my XF86Config-4 file, probably the driver in the Device section. Can anybody help me.

From PC-Chips web site:
----------------------------------------------------------------
OLD MB: PC-CHIPS M863G
   Chipset: SiS 741GX/964L
   VGA: Embedded Real256E 3D Graphics with 64M share memory

NEW MB: PC-CHIPS M871G
   Chipset: SiS 760GX/964
   VGA: Embedded Ultra256 3D Graphics with 64M share memory
        Embedded Mirage 2 Graphics with 128MB share memory
----------------------------------------------------------------

From my XF86Config-4 file:
----------------------------------------------------------------
Section "Device"
       Identifier      "SiS 630"
       Driver          "sis"
EndSection
----------------------------------------------------------------

The Identifier, while not accurate, doesn't really matter, but should the driver be changed? If so, to what? I tried googling for the VGA info and linux drivers, but got nothing useful. Can anyone point me to the correct info for this?
