On CentOS 5.4, the section "26.1 Structure of File Permissions" in "info chmod" states that the setuid bit has no effect on directories, but that the setgid bit does, on some systems, set the gid of files created in the directory.

The setgid bit certainly works for Samba group directories; we've never tried setuid.  I guess it may have worked in the past, but doesn't any more.  Try it from the command line: if it doesn't work there, it won't from Samba.
