Yes, I have.  In fact, lscape is what I am using.

I haven't changed the document at all, all I have done is upgrade Emacs which comes with org-mode v7.9.3f.

In fact, I just exported the document in on a different machine that has org-mode 7.8.11 installed, and #+begin_landscape/#+end_landscape works as expected.

Did you include the landscape package??

This

,----
| #+LATEX_HEADER: \usepackage{lscape}
|
| before
|
| #+begin_landscape
|
| here is some text
|
| #+end_landscape
|
| after
`----


gives me three pages using the new exporter. 'before' and 'after' in portrait
and "here is some text" in landscape.

HTH,
