Good news : this bug seems to be solved in the upstream kernel. I tried the Mainline kernel v3.4-rc6-precise (06-May-2012 22:56) [1] as I didn't found the *image*.deb in the v3.4-rc7-precise folder.
I was able to reboot, and halt my computer without problems (via the menu on the top right corner). I tried to reboot from a VGA console (I discover the name) but it went back to the "Alt + F7" view before I was able to read something.
