That is odd.  texi2dvi should default to using regular latex.  You usually have to pass a -p option or use the alias texi2pdf in order to use pdflatex.  It might be that you have a LATEX environment variable set.  In any case, you can alter this behaviour by setting the LATEX environment variable, e.g. setting the variable LATEX=xelatex will make texi2dvi use xelatex instead of regular latex.  

Finally, regarding .eps files, note that the latest version of pdflatex can handle .eps graphics without having to go through the latex->dvips->ps2pdf route so it might be worth your while upgrading.  Failing that, you can put \usepackage{epstopdf} in your preamble and then older versions of pdflatex will work just fine.

Just tried the texi2dvi command that is nice, one problem though, it
only makes use of pdflatex.

In certain situations, I like to use latex+ps2pdf (some journals ask for
.eps image file) or xelatex when mixing several fonts and writing in
UTF-8 is mandatory, for example French + Japanese, Chinese, Hindi, etc.

Currently I used the function below that I hook to the org-export-latex

AFAIK, providing one use few packages, a .tex file to be used with
pdflatex can be similar to one to be used with xelatex. The content of
the document (UTF-8 characters) will make the difference.

To circumvent this problem, considering pdflatex as the default option,
I add to the org file a:
"#+LATEX_CMD: xelatex" or "#+LATEX_CMD: latex"

Note: bibtex and glossaries compilation are detected by their call,
e.g. \bibliography

How about introducing a "#+LATEX_CMD:" option in org-mode? (and default
to pdflatex)

That also allow for customisation of the export of packages, for instance:

| ; Default packages
| (setq org-export-latex-packages-alist
|       '(("" "graphicx" t)
|       ("" "longtable" nil)
|       ("" "amssymb" t)
|       ("" "color" t)
|       ("pdfborder=0" "hyperref" nil)
|       ("" "float" nil)))
| ; Custom packages
| (defun my-auto-tex-parameters ()
|   "Automatically select the tex packages."
|   ; Default pdflatex
|   (setq org-export-latex-default-packages-alist
|       '(("AUTO" "inputenc" t)))
|   ; Look for xelatex call
|   (if (string-match "LATEX_CMD: xelatex" (buffer-string))
|       (setq org-export-latex-default-packages-alist
|           '(("" "fontspec" t))))
| (add-hook 'org-export-latex-after-initial-vars-hook 'my-auto-tex-parameters)
