737NG Vnav acceleration altitude

Just a quick question regarding the Vnav logic regarding the accel altitude after takeoff in the NG. Does the NG fmc + vnav command a pitch down for acceleration when Vnav is selected? I ask this because in the procedure guidelines I've seen the pilot is told to pitch down to 10 degrees and check accelerating before asking for VNav.
In the 744 and 767 there is an entry in the takeoff page of the fmc for acceleration altitude - Vnav will command a pitch change at this point for acceleration and flap retraction. The NG fmc does not have a entry for accel altitude - are different procedures needed (manual pitch down, disregarding flight director)?

Odd question I know, but someone may be able to help me. Cheers.
