I'm a bit confused by this question. My understanding is that
nvidia-detect looks up the card PCI ID in the various
/usr/share/nvidia/*.ids files and reports a positive match.

Are you saying those files may contain IDs that aren't supported
by the drivers? How are those files maintained? I poked around
the repository briefly and it seems it's mostly manual edits,
which seems fine apart from the risk of the odd typo.

In this case the drivers you package (thank you!) do support the card,
so the *.ids files seem to have the correct information.
