Assuming that you did not mess up somewhere on the way and your attempt
to patch the nvidia driver went the way you described, I would suspect
that the nvidia driver now has an alternative way to instantiate I2C
adapters (maybe hardware-driven vs. software bit-banged, I've see it a
lot in video and TV drivers.)
In this case, someone would have to find the new code and patch it in
the same easy was as was done for the original i2c code. This won't be
me though, sorry. I don't want to touch binary driver code for legal
reasons. You could give it a try, it's probably easy.

You are right. But on the other hand, nvidia's binary driver itself is
a hack, not a normal solution, so...
