Oh dear.  As the person who originally suggested using texi2dvi, I feel a
little bit responsible for all the trouble it has caused.  I wouldn't have
thought that such a widely used script would have a bug like this.

Anyway, one option would be to include a patched version of texi2dvi in the
org distribution, at least until the bug has been fixed in the official
version.  It is just a shell script, and not a huge file, so it wouldn't be
too bad.  Another option would be to simply inspect the contents of texi2dvi
and write equivalent code in Emacs Lisp, since the original idea was just to
improve the routines in org-mode that run pdflatex and bibtex.  Much of the
code in texi2dvi is to do with texinfo files and is irrelevant to how it is
being used in org-mode so this might not be as hard as it looks.

Finally, there are various LaTeX Makefiles available that attempt to build a
LaTeX document with a single invocation, much like texi2dvi.  They are
generally a bit less sophisticated than texi2dvi and I don't think that it
would be a good idea to use them directly because requiring make might be
problematic on Windows.  In any case, they might provide some helpful hints
on how to automate LaTeX compiling.  Here are links to three that I have
tried:

http://www.acoustics.hut.fi/u/mairas/UltimateLatexMakefile/
http://code.google.com/p/latex-makefile/
http://xpt.sourceforge.net/tools/latexmake/

I've had the most success with the third one, but that is essentially just a
wrapper for texi2dvi anyway.
