Are you using the D3DX mesh class? There's a sample in the SDK (Actually, I'm not certain if it's in the latest SDK) - the "Pick" sample, which shows how to do what you want.
Basically you call ID3DXMesh::LockVertexBuffer(), and test your line against all of the triangles in the buffer. I'm not sure how you get the triangles from the vertices however.
