    use "su -l"? this is on FreeBSD 6:

     By default, the environment is unmodified with the exception of USER,
     HOME, and SHELL.
     ...
     -l      Simulate a full login.  The environment is discarded except for
             HOME, SHELL, PATH, TERM, and USER.  HOME and SHELL are modified
             as above.  USER is set to the target login.  PATH is set to
             ``/bin:/usr/bin''.  TERM is imported from your current environ-
             ment.

    Password:
    You have mail.
    neuhauser# echo $USER $LOGNAME
    smradoch smradoch
    neuhauser# exit

    FreeBSD 6.1-PRERELEASE amd64

    su (coreutils) 4.5.3 on RHEL3 behaves exactly the same.
