I get this as well. Indeed it's intended to be able to just press enter, or typeahead your user name, but it recently broke.
It seems to correlate with bug 439138; in the situations where gdm is misbehaving, I also get the "X uses 100% CPU" bug. After restarting X, it seems to work again.
It is conceivable that both bugs have the same source: X desperately trying to claim the VT, which cryptsetup also holds, and there's a conflict with both things wanting to grab the keyboard/console.
Can anyone confirm this? Please add the system monitor applet for watching the CPU usage. When you get the bug, do you get a constant 100% CPU usage? If you log out and back in, is it fixed, and does gdm react to just pressing enter for the user name?
