I'm a bit lost here. In particular, I'm able to export the example above
out-of-the-box, provided I add "#+options: tex:dvipng" or some such in
the document.

I don't think you need to modify `org-format-latex-header' at all. There
is `org-latex-packages-alist' for that.

So, is there a bug in the ODT export back-end? If so, could you post an
ECM? Loads of LaTeX code doesn't help understanding the issue.
