Hi,
Sorry for replying to an old message, but nobody has
responded to this particular question, so I give it
a try ...

You can use the backslash sequence '\c' with echo -e, which
has the same effect as the -n option. See sh(1).
Another possibility is to use dd(1) to strip off the new-
line (dd(1) lives in /bin, so it's available during boot).
A shell function like this does it:
echo-en()
{
x="$*"
echo -e "$x" | dd bs=$((${#x}-1)) count=1 2>/dev/null
}
Although it's a bit less efficient because dd(1) is an
external binary, it's more flexible since it can be used
for all kinds of cutting and trimming (note that cut(1)
resides in /usr/bin).
Best regards
Oliver
