I don't see the problem, the text above clearly explain the reason.
And according to questions on freebsd-questions@,, the main problem is
the fact no one read the "existing" documentation; For example, a recent
thread about DVD burning speed/DMA issue... with the solution documented
in many places...
However I can understand your point of view regarding the fact the
manual page do not even mention briefly the "invisible" options. A
volunteer should write a patch against the manual page and send it to
