I extracted the driver CAB files and imported them in exactly the same way as I have for the other models but I encountered the 'Cannot import this driver as it already exists in this site' issue.

The CAB file seems to be missing a lot of the release.dat files that have been added to other driver packages to circumvent the duplicate driver detection process of ConfigMgr. The release.dat files that are included in some of the folders refer to the 760 model.
