Happens for me using 32-bit w/nvidia on a Latitude D630. It's as if the Enter key was remapped to a "system freeze" function. I can log in and do many tasks using the mouse to click through confirmation dialogs, but as soon as I hit the Enter key, be it at the terminal or to press a highlighted button, the system freezes and cannot be recovered. Only holding down the power button will power it off (I did not try the alt-sysRq+b sequence.)
Removed the "plymouth" package through aptitude in the recovery console and now it's fine.
