I finally find a way to deactivate framebuffer:
I blacklisted module vesafb, launch update-initramfs -u and reboot.
At reboot I had error messages (file not found) and the uglier plymouth animation I seen, good sign of a lack of framebuffer.
Effectively, if I do a:
$ lsmod |grep fb, nothing appear
in dmesg, there are no more error messages
Good, framebuffer is off, I try to access to my TTY console, nothing, black screen then my monitor suspend.
I finally revert all my configuration like it was before.
Now I have just to wait they will correct this bug soon.
