I suppose this is a getpass() problem ?
This is intended operation as su(1) may not always be affiliated with a
TTY. This leaves it open for a script to chat with much like what samba
does with its passwd chat mechanism.
just to feed the debate :
aix 5.2 : prompt to tty
hp-ux : prompt to stderr
netbsd : prompt to tty
solaris 9 : prompt to stderr
solaris 10 : prompt to tty
openbsd : prompt to tty
ubuntu : prompt to stderr
freebsd is the only one which prompt to stdout !
IMHO, it should at least prompt to stderr if not tty...
and report errors to stderr as usually.
