When you're running in text mode (no X11) the console is the tty you're in front
of. An xterm is just another tty, not the console. Just as you won't see
console messages on a telnet connection or if you're logged in on a serial line
or such like.

Or man xterm:
[...]
-C This option indicates that this window should
receive console output. This is not supported on
all systems. To obtain console output, you must
be the owner of the console device, and you must
have read and write permission for it. If you are
running X under xdm on the console screen you may
need to have the session startup and reset pro
grams explicitly change the ownership of the con
sole device in order to get this option to work.
It does depend on the OS. Haven't tried this with Linux myself.

If -C doesn't work on linux you can always go:
xterm -e tail -f /var/log/messages
which would do passably.

Perhaps not readily. And I suspect you don't want the messages in _every_
tty (which the above appears to want, though it wouldn't do it). You
could go:
xterm -e a-script
and write the "a-script" script to edit that line of the syslogd.conf file
to say
kern.* /dev/ptyXX
where /dev/ptyXX is the output of the "tty" command. Then prod syslogd to
reread things.
The problem with that is that if your tty goes away for some reason the
messages now go nowhere. Undesirable. It is better (if it works) to use
"xterm -C" and leave the messages directed to /dev/console, which is a
nice reliable place.
