heh this is very interesting.... top b n1 reports this:
top - 10:08:24 up 16:36, 2 users, load average: 0.16, 0.19, 0.08
Tasks: 62 total, 1 running, 60 sleeping, 0 stopped, 1 zombie
Cpu(s): 12.3% user, 5.1% system, 0.0% nice, 82.6% idle
Mem: 385904k total, 381572k used, 4332k free, 137244k buffers
Swap: 128512k total, 20012k used, 108500k free, 126168k cached

while gkrellm reports that my RAM used is 95MB. now this is interesting....

here is the /proc/meminfo:
