I tried on my both machines 32mb and 16 mb got these results
ls -l /proc/kcore | awk '{print $5}'
33558528
cat /proc/meminfo

cat /dev/mem | wc -c ;; shows installed mem

echo "1024*1024*32" | bc ;; real installed mem

echo "33558528 - 33554432" | bc ;; kcore - installed mem

echo "33554432 - 31264768" | bc ;; installed mem - reported mem

ls /proc/kcore -l | awk '{print $5}'

4096
see the difference between kcore size and installed mem
is always 4096, is it something to do with shadow ram
or video memory ?
i will run a series of tests with all sort of configs and
post the results to some place, in a week
