I found the problem. I have fooled myself:

root at zoo:/lxc# psg lxc
USER       PID  PPID %CPU    VSZ COMMAND
root      3800  1433  0.0   8508 /usr/bin/lxc-start -f egal.cfg -n egal

root at zoo:/lxc# /usr/bin/lxc-console -n egal

Type <Ctrl+a q> to exit the console
root at egal:~#

root at zoo:/lxc# lxc-console -n egal
lxc-console: 'egal' is stopped

root at zoo:/lxc# type -a lxc-console
lxc-console is /opt/lxc/bin/lxc-console
lxc-console is /usr/bin/lxc-console

/usr/bin/lxc* is the offcial Ubuntu 10.04 lxc package, whereas /opt/lxc/*
is my addon installation of a newer lxc versiom. Mixing both is a BAD idea.
Sorry for the confusion.

Wrong :-)
I have modified /etc/init/tty*.conf inside the container, because I do not
want to have a login prompt, but a root shell.

root at zoo:/lxc# cat egal/etc/init/tty1.conf 
# tty1 - getty
#
# This service maintains a getty on tty1 from the point the system is
# started until it is shut down again.

start on stopped rc RUNLEVEL=[2345]
stop on runlevel [!2345]

respawn
exec /bin/openvt -elfc 1 -- su -l
