This is a problem which was discussed on this ML as a follow-up in the
tread "[PATCH] ppc32: Rework power management take #3" The problem seems
to ba that the kernel crashes if you switch away from X to a terminal
that was not allocated before the first X-Server started. Since your
second XServer switches the tty when you start it, the machine crashes.
Benh said that he would look at it, but I think he had no time to do
that yet.
