   does work as expected.

  Yes, but I would not call the above construct elegant, so having
  something cleaner and more accessible for the average user would be
  nice. John Palmieri posted a patch to trac, so hopefully it will be
  reviewed soon.

 Well, I *hope* to post a patch to trac soon, but I haven't actually
 done it yet.

   John

Try this out:

  http://trac.sagemath.org/sage_trac/ticket/5791

and see the pictures at

  http://sage.math.washington.edu/home/palmieri/misc/foobar.png

I haven't tried it with tikz, by the way.

 I am happy to report the functionality to modify
 the latex header for notebook output is already present in sage:

     sage:  import sage.misc.latex as l

     sage:  l.LATEX_HEADER+='\\def \\pgfsysdriver {pgfsys-dvips.def}\n
                                               \\usepackage{tikz\n
                                               \\usetikzlibrary
 {shapes,fit,positioning}\n'
     sage:  print 'LATEX_HEADER\n', l.LATEX_HEADER

 does work as expected.
 Next, a cell with the following text:

    %latex
       \begin{tikzpicture}[=stealth]
       \draw[red,rotate=10,scale=.5,ultra thick] (0.375,0) ellipse
 (1.125 and 2.0945);
       \end{tikzpicture}
       oh?

 will produce an ellipse with the string oh? to the left.
 Without oh?, however, I get not output at all???

 -puzzled

I have no idea, but you could try %latex_debug instead of %latex to
get some more information about what's going on.
