Likewise, my initial assumption was that GNOME System Monitor was 
faulty.  You might try the command that I suggested in my original report:

    watch -d -n 0.25 'cat /sys/class/net/eth0/statistics/rx_bytes'

Run that during a big download and it should be pretty clear whether 
it's being updated frequently or not.  If not, then gkrellm is not to blame.
