Here is a small patch to turn off splash/saver upon opening a vty, as
suggested by Guido. It is for /sys/dev/syscons/syscons.c.
Ken, when xdm starts, whether by a local rc script or via /etc/ttys,
it is very soon after vtys are opened. So you shouldn't see text
console for very long. Please try the patch and tell me if you still
think the text console is exposed for too long for your environment.
