Additional info:
Comment 1 thompson 2001-05-08 15:08:56 UTC 
"free" command appears to have the same problem.
Comment 2 thompson 2001-05-08 15:17:58 UTC 
Seems to stem from /proc/meminfo being incorrect....
Comment 3 giulioo 2001-05-08 21:36:23 UTC 
It seems this is expected behavior, at least in the 2.2.x RedHat patched kernel.
2.4.x dropped shared memory reporting for performance reasons.
