I have no information about this ; I'll try to follow these links next week.

Yes, perfectly for me with grml or debian.

I don't understand exactly what you mean ; nevertheless, I'll try to answer
as best as possible :

1) with the correct boot option (for me brltty=pm,usb:,fr_FR), there's
   nothing more to do ;
2) without the boot option, after the tones in grml_2011.12, without any
   boot option about language, I have to use the -t option on the
   commandline ; but for someone connected with something else than usb,
   the -b and -d options are mandatory.

I hope this is the answer you are waiting for :-)

Shall I  se the bootoption style or the commandline style ? I guess the
command line but...

I think you mean grml_2011.12.iso or is it a mistake from me ?

And in the -b parameter, shall I, for instance, type : "lang=fr scripts" ?

This is perfect for me but I fear it's a little complicated for other blind
people I know :-)

I should have used {$OVERLAY_DIR} or simply $OVERLAY_dir ; am I wrong ?

I'll try this as soon as possible but not this new year week-end.
