For OS 10.9 "Mavericks" Apple has included support for signed KEXTs, non-signed KEXTs will generate a warning dialog to the user.
Signing keys cannot be included in the git repository, however a README note should be included, and the "official" installer should use a signed copy of the KEXT. For more information see the Apple WWDC presentation "What's New in KEXTs"
