Looking at the relevant code in contrib/org-exp-bibtex.el, I managed to
produce the following, which *almost* works:

    (defun org-export-bibliography-preprocess ()
        "Insert \bibliography and \bibliographystyle commands at end
    of buffer if keyword `#+BIBLIOGRAPHY <file> <style>' is present in
    buffer when exporting via latex backend."
        (interactive)
        (save-excursion
            (goto-char (point-min))
            (while (re-search-forward "^#\\+BIBLIOGRAPHY:[ \t]+\\(\\S-+\\)[ 
\t]+\\(\\S-+\\)\\([^\r\n]*\\)" nil t)
                (let ((file  (match-string 1))
                      (style (match-string 2)))          
                    (when (eq org-export-current-backend 'latex)
                        (goto-char (point-max))
                        (insert
                         (concat "\n#+LATEX: \\bibliographystyle{" style "}"
                                 "\n#+LATEX: \\bibliography{" file "}\n")))))))
    
    (add-hook 'org-export-preprocess-hook 'org-export-bibliography-preprocess)

Unfortunately, it inserts the latex directives twice, one near the top
of the buffer, and the other one at its end, as expected.  Any ideas why
that is?
