Bonjour Ben, merci pour le suivit.

Does this happen also without radeonfb and with X alone using the X
"radeon" driver ?
Yes, unless I misunderstand you. I tried several options at the yaboot
prompt (nofb or video=of), and speaking of Xorg, I don't use the
UseFBDev for X11 since it rarely works with LCD panels (same with the
Apple 20" and the Samsung 206, most of the valid resolutions don't work
with UseFBDev).
Here are my device and monitor sections of xorg.conf:
