Also, I'm not sure what you mean by 0xBABA. That would be an interesting coincidence if the checksum was 0xBABA, but the checksum should be recalculated when the iNVM is changed. There could be a chance that whoever programmed the part was using an older broken version of the programming tool.
The reason you may not see the i211 specifically mentioned is because the parts are in an enum and very often we just refer to the i210 & i211 with an inequality. You should contact whoever sold you the parts first. We can also put you in touch with our local representatives in Europe who should be able to help you further with the iNVM. Thanks.

Have you tried to update the BIOS on this (these) system(s)? A lot of time the NVM is updated during a BIOS update. So I'd start there.
