<confrontation mode=head-butt>oh yeah? looks to me like this only checks
whether you're running under an X-window *term versus the console, not whether
you're logged in as root. aha! gotcha!</confrontation>

here's my iteration on top of your stuff, and <flameproof suit at hand> please
feel free to gimme pointers on how to make this (particularly colors) more
modular...

function munge_ps1
{
	local TITLEBAR=''
	local PROMPT='$'

	if [ "$BASH" ]; then
		local COLOR='43;34;3'
		if [ $EUID = '0' ] ; then
			COLOR='41;33;1'
			PROMPT='#'
		fi
		PROMPT="\e[${COLOR}m\u@\h\e[37;40;1m: \w \e[0m\n${PROMPT}"
	else
		if [ "`id -u`" -eq 0 ]; then
			PROMPT='#'
		fi
	fi

	case $TERM in
		xterm*|rxvt|eterm|wterm)
			TITLEBAR='\[\e]0;\u@\h:\w\007\]'
			;;
		*)
			TITLEBAR=''       
			;;  
	esac

	PS1="${TITLEBAR}${PROMPT} "
}
