same thing happened to me on a feisty live cd (build 2007-02-18) Chose the German keyboard layout during install. When I entered the username and password the keyboard setting must have been in english. My password had a "y" in it and I ended up with having to type a "z" instead of the "y" on my first logon to the system.
