Are you sure it worked with beamer? AFAICT, it just adds a subtitle
to the title slide, nothing more. In particular, beamer does not seem
to use it for the purpose that Seb wants it: a (limited-length) marker
on each slide.
Tested with this:
--8<---------------cut here---------------start------------->8---
#+LaTeX_CLASS: beamer
#+LaTeX_CLASS_OPTIONS: [presentation]
#+BEAMER_THEME: Madrid
#+COLUMNS: %45ITEM %10BEAMER_env(Env) %10BEAMER_act(Act) %4BEAMER_col(Col)
%8BEAMER_opt(Opt)
#+PROPERTY: BEAMER_col_ALL 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 0.0 :ETC
#+TITLE: A very long title that will overflow the box that beamer allocates for
it on each slide
#+LATEX_HEADER: \subtitle{A shorter title}
* Slide 1
*** Item 1
