Graphic cards are seldom forward compatible.

As far as I know, NVidia 8 supports DX10 fully hardwarely. But You also may install DX10 on older NVIdia card (6,7 Series) -- in this case DX10 features will softwarely simulated.

From wiki:
http://en.wikipedia.org/wiki/Shader_Model_4

"Optionally, an application using a Direct3D10 interface and Direct3D10 hardware may also specify a geometry shader. This shader takes as its input the three vertices of a triangle and uses this data to generate (or tesselate) additional triangles, which are each then sent to the rasterizer."

D3D10 supports geometry shaders. There is simply NO point in emulating a geometry shader in software. You'd render all geometry directly in that case.
