So, if you stick to the generic path in OpenGL you are sort of at a combination of DX8 and 9?
Yeah, NV_VertexProgram, was equivelent of DX8 Vertex Shader, and ARB_VertexProgram is pretty much the same as the nvidia one.

I dont know what changed in VertexShaders from DX8 to 9.

DX9 shaders are the first to have a high-level language with them. Previous shaders were all done using assembly shader ops.
You can actually create NV2X style Pixel shaders and Vertex shaders in Cg, so technically they were the 1st to have a high level language. Although its not very flexable for those profiles, and didn't come out until months after Cg debuted.
