Indeed with Alex's line in the blacklist there is no problem and the boot time has been dramatically improved; no camera of course. I am a new newbie and I just wrote that the power manager might be the problem because it doesn't use the latest upower version (0.9.4) but a previous one. I've tried to update the upower but then I encountered a problem with the glib that was not found (! although I can see it in the synaptics). In any case at this point speed is more important to me than the camera.
