I'm a bit confused regards what you said about the math node so I tried it they way I've been doing it. I just drive the Displacement directly from a 2D Image Node and it works, it gives me both positive and negative displacement even without a math node, and with ZBrush displacement set to 0.5.
I've pulled everything into one screenshot to show you what I mean. Note that although the"Mid" control is greyed-out now in ZBrush, it actually is set to 0.5, it's just that 0.5 isn't half way along the slider. But yup, didn't need to do anything fancy, all I did was a quick low-res displacement, flipped it vertically and exported it with the "Mid" slider set to 0.5.
In Poser, it just drives the Displacement directly, no math node needed, I just set to 0.007500 out of preference.

Just in case you're curious what displacement controls ZBrush has, check-out the basic Displacement Panel that's open in this screenshot. There's another Displacement panel as well, for "Vector Displacement" but I've not even looked into that one yet - I don't think I need it.
