[Grml] Accessibility in the grml 2011.12

Hi all.

I had a look to the Release Notes for Grml 2011.12-rc1 and something seems very unclear to me :

* The accessibility support now consists of shipping standard speakup and enabling sound during boot. A new beep sequence (4 tones) is sounded just before the quickconfig menu starts. (The boot options have been removed.)

When I hear the 4 tones, is it time to invoke brltty ?

I don't really understand the meaning of « the boot options have been removed».

And when shall I choose lang=fr ?

Thanks for explanations.
