I like the second one, will that display fine everywhere? I've not seen those characters before.
It will display via SSH w/ putty, VT100, Linux Terminal, xterm, xterm256 color, etc.. common defaults work fine.
I replaced /etc/banner with this and logged into one of my S3's w/ putty (default settings)
