SubjectRE: Shared memory not enabled in 2.4.0?

You are confusing System V shared memory (IPC) with VM shared memory. The
'0' for shared in /proc/meminfo means the system can't easily tell you how
much memory the VM is sharing. But this has nothing whatsoever to do with
IPC shared memory, which is what the /dev/shm thing is about.
