BTW, If anyone really wants scrolling, this script should do it.  It has
to use character 16 for spaces, which is a bit broken -- YMMV.

====================
#!/bin/bash

STR="Linux $(uname -r)   "
END=""

# Prevent the PDC from stripping leading spaces by
# using character 16 (octal 20) as a space...

STR="$(echo "$STR" | tr ' ' '\20')"

while(true); do
	echo "${STR}${END}" > /proc/pdc/lcd
	END="${END}${STR:0:1}"
	STR="${STR:1}"
	if [ -z "${STR:-}" ]; then
		STR="${END}"
		END=""
	fi
	sleep 0.25
done
