Yes, it worked !
You have just earned 20 EUR :)
Now my external VGA display finally works properly in both Mac OS X and
Debian GNU/Linux 4.0
Here's the detailed information:

Perhaps a dumb question but...
I don't need the external vga ouput all the time. In fact I only need it
when I make presentations with a beamer, that is once every three months.
Should I keep using the xorg.conf with the external VGA output defined even
if I don't need it ?
Will it "suck" more energy from the battery if I leave the VGA ouput enabled
in xorg.conf ?
Leaving the DAC enabled will draw more power. If you want to try the
randr-1.2 branch of the radeon driver, it allows you to turn outputs
on and off on the fly and even switch between dualhead and single head
on the fly. It requires a newer X server and xrandr however.
