I tried the following :

-> I recompiled the latest QEMU version with "--enable-gtk" : my guest is now 
launched in a window with a "menu" with "Machine" and "View" entries above but 
I still have the same black screen issue and I can't switch to QEMU monitor 
window anymore (ctrl-alt-2 does not work)...

-> I also tried to redirect console in graphic window and not in stdio/ttyAMA0 
and the last line I see (stucked on it around 10s perhaps) before window goes 
black is : "Console: switching to color frame buffer 80x30" Does it rings a 
bell to you ?

-> I activated the vnc server using QEMU and I still have the same refreshing 
issue in the VNC client (vinagre).

-> I performed a "init 0" in the QEMU graphical window and even if the text was 
not displayed (display not refreshed), guest turned off when I pressed "enter"

Do you have some leads to debug this refreshing issue ?
