Gets Around
It seems to me that it's not working. In the following code geometry and energy are the same in the presence and absence of "disp vdw 3".

start nw
charge 0

geometry   
 He      0.00000000000000   0.00000000000000  -1.40439630000000  
 He      0.00000000000000   0.00000000000000   1.40439630000000  
end 

basis spherical

Geometry optimizations within DFT Gaussian basis set module can be done for all DFT functionals.

disp vdw 3
end
