hmm, no. After the S3 site, I expect the pci ids to be something like that :

5333  S3 Inc.
         8e00  DeltaChromeS8 (AGP)
         8e01  DeltaChromeX9m (AGP)
         8e02  DeltaChromeX9m ULP (AGP)
         8e03  DeltaChromeM (AGP)
         8e04  DeltaChromeS4 (AGP)
         8e10  GammaChromeS18 (PCIe)
         8e11  GammaChromeXM18 ULP MPM32 (PCIe)
         8e12  GammaChromeXM18 (PCIe)
         8e13  GammaChromeXM18 ULP MPM64 (PCIe)
         8e40  Chrome S23 (PCIe)
         8e41  Chrome XM23 (PCIe)
         8e48  Chrome S25/S27 (PCIe)
         8e4a  Chrome XM27 (PCIe)
         8e4c  Chrome XM25 ULP MPM-64 (PCIe)
         8e4f  Chrome XM25 ULP MPM-128 (PCIe)

The openchrome driver will probably need a lot of changes to be able to 
drive the S3 chips, if possible at all. Again, hard to tell w/o the docs 
and/or the hardware.
