Okay, the patch works. However, I can still reproduce the
problem if I use a slight variation on the first keymap.
090 cr rctrl nl nl rctrl rctrl nl nl O
Press and hold Alt, then press rctrl. Release all keys. Then
press `d' or whatever and you'll log out.
[If X is running, you can switch to X and then switch back to
your text console and the keyboard state will return to normal]
The patch, as shown, is good enough for me, since the keymap one
would have to use to reproduce the bug now is not very useful
(for me, anyways).
