OK, but you've still not shown that you didn't accidentally make a 
mistake somewhere along the way.

I asked you to confirm the exact steps you took because something 
doesn't make sense, so it's important to show what you actually did 
rather than retyping from memory what you think you did, in case you had 
made a mistake without noticing it.

Here is the output of a FreeBSD 8.0 system showing that LOCK_PROFILING 
does in fact work as expected:
