Oh that explains it. I've seen that on releng7. I'll update
the current version.

Without the KDTRACE_HOOKS option, the modules should fail to
load via kldload. I guess that checking isn't possible if the
modules are loaded from boot.

BTW, as a committer it might be more convenient for you to use
the sources direct from the perforce server in
//depot/projects/dtrace.
