Let me add a qualifier: if you try to preview the image, then it does
not seem to work, but that seems to be a characteristic of tikz/pgf,
rather than org-mode.

Here's the experiment, should somebody care to try it:

o Start with a simple picture - the one waterloo posted earlier in
the month will do:

,----
| #+LaTeX_HEADER: \usepackage{tikz}
| 
| * Draw
| 
| \begin{tikzpicture}
| \draw (0,0) -- (10,0);
| \end{tikzpicture}
`----

o Export it to LaTeX with C-c C-e l.

o Process the latex file with pdflatex and view with xpdf - everything
is fine.

o Process the latex file with latex, producing a dvi file.  View the dvi
file with xdvi: the picture is missing (and I get a Ghostscript error.)

o Process the dvi file to PS with dvips and view the resulting PS file:
the picture is there.

Since (I'm guessing) preview processes the dvi file with dvipng and
since the dvi file seems to have some kind of problem, preview does not
work.

HTH,
