man kextlibs:
-unsupported
Search unsupported library kexts for symbols (by default they are
not searched).
That will get you your unsupported kext libraries, if they still define those symbols. You can also use kextfind's -defines-symbol (-dsym) predicate:
kextfind -defines-symbol _mac_vnop_getxattr
