Well, I'm not positive that this is the best way or the that it will work
correctly under all instances but if you have read access to the /dev/mem
(or /dev/kmem) you might just try
'wc -c < /dev/mem' using the word count program to count the number of
bytes.  I've found on most systems that it will return the correct physical
memory size (not swap space though).
