Can I use SDL_BlitSurface or must I use some OpenGL calls?  Some sample code that also has the call to SDL_GL_SwapBuffers would be much appreciated.

 Pass SDL_OPENGLBLIT to SDL_SetVideoMode() instead of SDL_OPENGL,
then use gl calls and SDL calls as you normally would, including
SDL_GL_SwapBuffers() to swap the gl buffers and SDL_Flip/SDL_UpdateRect(s)
to update the 2d stuff you draw with SDL calls.
