Okay, the beloved style system does not let me debug it.  The
condition for not loading the style file is probably the `unless'
statement in `TeX-run-style-hooks' but I cannot prove that with a
debugger.

Not so nice as the original form above but working better is this:

(add-hook 'LaTeX-mode-hook
          (lambda ()
            (when (member "beamer" TeX-active-styles)
              (TeX-add-style-hook "beamer" (lambda () (TeX-PDF-mode 1))))))

In order to make this more userfriendly we could let `TeX-load-style'
run a hook (with the style name as argument).
