--- Comment #26 from Jason Detring <detringj-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> ---
Works well, just needs the chipset ID swapped.

-       { PCI_VENDOR_ID_VIA, PCI_DEVICE_ID_VIA_8363_0, PCI_VENDOR_ID_NVIDIA,
0x0311, 2 },
+       { PCI_VENDOR_ID_VIA, PCI_DEVICE_ID_VIA_82C691_0, PCI_VENDOR_ID_NVIDIA,
PCI_DEVICE_ID_NVIDIA_GEFORCE_FX_5600_ULTRA, 2 },
