The DC9 does not have a STICK PUSHER.
A really fine piece on T tail and deep stall is located at:

and might prove an interesting read.
I also recall in the early days of understanding T tail and deep stall etc, that if presented with a high nose attitude, one could consider rolling by use of ailerons to recover.
The DC9 has aerodynamically powered elevator...at extreme aoa this was insufficient to move elevator for recovery, so sort of a hydraulic ram was installed and by moving yoke full forward would activate to move elevators...
those of you who taxi behind a DC9 or MD80 may notice the elevators are NOT always symetrical (especially with tail wind), just prior to takeoff you are supposed to push yoke forward to "ram" the elevator down...once rolling for takeoff the air flow is sufficent to control the elevators. Even if you didn't "RAM " the elevators down, it would all sort itself out by about 40-50knots or so.
