Before draw_vbo is called, the vbo will have been set up via
pipe->bind_vertex_elements_state and pipe->set_vertex_buffers. The
draw call will then validate those, by calling nv30_state_validate (or
something along those lines) which will look at all the dirtied state
and write that out to hw.

There are also funny interactions with translate... for formats that
aren't directly supported.
