How many of those platforms have buggy su, though? NetBSD didn't,
pre-PAM.

For those that do, might it be simplest to install a little wrapper
for su, e.g.:

#!/bin/sh

SU=/usr/bin/su

test $# -ge 1 || set -- root

unset endopts
for i
do
  case "${endopts+set}:$i" in
    :-- | :[!-]* )
      shift
      set -- "$@" "$i" -c 'exec 0<&9 9<&- "$SHELL" "$@"' dummy
      endopts=
      ;;
    :-* | set:* )
      shift
      set -- "$@" "$i"
      ;;
  esac
done

exec 9<&0 0</dev/tty "$SU" "$@"
