At the boot time, using advanced options and selecting the old kernel (3.2.0-4-amd64), I got the brightness keys back to work. This way, I think it's a kernel related problem. Does anyone have any idea of how I could fix it or where I must search for answers?

Unfortunately, xbacklight doesn't work in this machine. Any other idea?
