Thanks for your input Marc. I tried with radeon. Unfortunately it was
not that.

Nevertherless I could learn something:
1920x1440:  git=black screen;  6.9.0-1+lenny2=ok
1280x768:   git=flicker;       6.9.0-1+lenny2=flicker 
flicker means, the screen appear shortly, then turns black, reappear
shortly...

So I learned that:
- even if 6.9.0-1+lenny2 works in 1920x1440 works, git does not work
- both does not work in 1280x768 (suprising knowing it should be easier
  to display)
=> looks like it is not a problem of dual-dvi vs single-dvi

Note that I didn't use checkinstall but:
   # aptitude build-dep xserver-xorg-video-ati
   $ git clone git://anongit.freedesktop.org/git/xorg/driver/xf86-video-ati
   $ cd xf86-video-ati/
   $ ./autogen.sh --prefix=/usr
   $ make
   # make install

So to be complete I usually do:
   # aptitude build-dep xserver-xorg-video-ati
   (delete previous git if existing)
   $ git clone git://anongit.freedesktop.org/git/xorg/driver/xf86-video-ati
   $ cd xf86-video-ati/
   $ ./autogen.sh
   $ make
   # make install prefix=/usr
then restarting X with ctrl-alt-backspace

Then to reinstall original radeon (after it failed)
   # aptitude reinstall xserver-xorg-video-ati
   # aptitude reinstall xserver-xorg-video-radeon

Again thanks for having tried to help me,
Franck
