Basically the first thing done each frame is that a very small gray circle (16pixels X 16 pixels) is drawn over and over again (by setting it as the active texture and flushing loads and loads of vertices) in order to shape the current minimap (actually, this only shapes the background of the map). Once this is complete, the EFB is copied to some location in memory and cleared. Then the rest of the frame begins drawing, and at some point later, the map is drawn back to the frame as a texture in its proper place. Right after this things like the location indicator, etc. are drawn to the map.
At least in the GC version, the location indicator is drawn at the same time as the rest of the minimap, not added later. This can be seen in the attached snapshots of the efb just before clearing. The colors are probably added later using a palette. There is the possibility of the game copying the frame out and in again just after targ2317, but i doubt that.
