FWIW, they don't work for me either (I also have an extended keyboard). 
Pressing one of the arrows yields an escape sequence like ^]0A to ^]0D,
depending on which key was pressed.  I also have an extended keyboard on
my other Mac, and when I telnet into the NetBSD box the arrow keys work as
expected.  I've tried this with $TERM=vt100 and with $TERM=vt220, as well
as inside and outside of dt.  Not a significant problem, but definitely a
minor annoyance.
