It could just be a very busy network with lots of traffic, but then your ifconfig eth0 says "Collisions:0". Are you on a switch?
Another option would be to see if your card is running in full-duplex mode and the hub/switch is in half duplex (or vise versa) apt-get install nictools-pci there may be a cardbus/xircom diagnosis program in there.
