If the KEXT could be installed in a custom location (/Library/Application Support/foo/bar for example) so that the system will not load it automatically, then a launchd daemon could be used to verify the KEXT's integrity before loading it.

Thanks,
Ameen.

Wait ... the root filesystem isn't mounted when kexts are loaded?  And
kextd is running?  How does THAT work?  I will freely confess that when
I did this it was well pass system boot time, so obviously the root filesystem
was mounted.
