How do you determine the amount of system memory?

[Paul Lussier]

Hi all,

Recent Linux kernels have had a minor bug in that the amount of memory
reported in /proc/meminfo is incorrect.  I'm trying to find a way to
determine whether the amount reported is correct or not.

I need some means of reliably knowing whether this value is accurate
or not.  Does anyone have any ideas?  "Physically looking" is
insufficient, given that I a) need to test 400+ systems, and b) I may
need to run this test on boxes to which I have no physical access.

Thanks.
