No.  Read http://x.cygwin.com/docs/ug/using-shared-memory.html again.
It says exactly what you need to do to get XSI shared memory running.
The *note* is for 1.5 only.

(*) Btw., named POSIX shared mem support is available since 1.7.  It's
    a pity that MIT-SHM extension uses XSI, rather than POSIX shared
    memory, since you don't need cygserver for the POSIX implementation.
