What supports your claim that the referenced commit breaks early
module loading ? You even did not provided the panic message, btw.
Commit only changed the wrapper around kldstat(2) syscall, that cannot
be used during bootstrap, and the changed code does not reference kldstat(9).
The later cannot prove that the change did not break something, but
due to its nature, it is unlikely.
