It seems I can.  I just pulled the master branch
(Org-mode version 8.3beta (release_8.3beta-517-g86d1a7))

I start emacs -Q -l emacs.minimal
where emacs.minimal is

(add-to-list 'load-path (expand-file-name "~/local/emacs/org-mode-install/lisp"))
(add-to-list 'auto-mode-alist '("\\.\\(org\\  |org_archive\\|txt\\)$" . org-mode))
(setq org-agenda-files '("/tmp/test.org"))
;;(require 'org-install)
;;(require 'org-habit)

(add-to-list 'load-path (expand-file-name "~/local/emacs/org-mode/contrib/lisp"))

(global-set-key "\C-ca" 'org-agenda)

(org-babel-do-load-languages
 'org-babel-load-languages
 '((R . t)
   (latex . t)
   (emacs-lisp . t)
   (sh . t)))

I open this file:

--8<---------------cut here---------------start------------->8---
#+TITLE: Test amsmath's split

* Some equation
with some split expression, e.g.
\begin{equation}
  \begin{split}
    w \cdot x + b &= 1, \text{ and}\\
    w \cdot x + b &= -1
  \end{split}
\end{equation}

To reproduce try to org-toggle-latex-fragment (C-c C-x C-l) on that
latex expression.

Export of this works fine.

I try to preview my equation and get this tex:

What do I miss here?
