Update the pcitable, Cards, and pciids.sf.net to match what is supported by the current "cyrix" and "nsc" drivers in Xorg X11.
This one is tricky, because the cyrix and nsc drivers share the same PCI IDs with a bit of overlap. As such, there is no way to uniquely determine which driver should be used. We should just ensure the PCI IDs all exist in pcitable and map to some driver. The problem of which driver to use is deeper and should be dealt with upstream in X.Org instead.
Rawhide hwdata is up to date with 6.8.2 for this driver. The cyrix/nsc PCI ID confusion is a problem that needs to be resolved upstream in the respective drivers. I've filed an upstream bug report for that problem. https://bugs.freedesktop.org/show_bug.cgi?id=2737
