Shared memory not enabled in 2.4.0?

[Steven_Snyder@3com.com]

For some reason shared memory is not being enabled on my system running kernel
v2.4.0 (on RedHat v6.2,  with all updates applied).

Per the documentation I have this line in my /etc/fstab:

     none  /dev/shm  shm defaults  0 0

Yes, I have created this subdirectory:

     # ls -l /dev | grep shm
     drwxrwxrwt    1 root     root            0 Jan  7 11:54 shm

No complaints are seen at startup, yet I still have no shared memory:

     # cat /proc/meminfo
             total:    used:    free:  shared: buffers:  cached:

     SwapTotal:      133048 kB
     SwapFree:       133048 kB

Is there some configuration option which I missed?  Some trick not mentioned in
the doc?

Thank you.
