I'll have something better out by that time, but for right now I use a modified init. This relies on the sound program on the developer site and Kim's graphic program. But I have some ideas and want to add a rotating option to it, so that it can use different graphics or sounds. For now, here is what mine does:

#!/sbin/sh
echo "*** Empeg Startup Script v0.20 ***"
echo "*** Displaying Graphic ***"
/sbin/dispgraphic < /usr/startup/display
echo "*** Playing startup sound ***"
/sbin/pcmplay < /usr/startup/sound
echo "*** Starting Player ***"
exec /sbin/init.org

My empeg site is:http://24.236.3.131/empeg/
