No, since they have a different scheduling policy than all normal niced processes and don't behave like nice -20 (nice = +20) processes. They sort of behave like nice -21 through nice -52 processes. top(1) has a hack which are supposed to display them as having the fake nice values 21 through 52, but it is broken in -current by much the same kernel changes that break the display of rtprio values in ps(1) (see my other reply to this thread).
