Thanks for the info. I'll try compiling a driver.
This is the info I have on the NIC: (taken from a live DVD of Ubuntu)
ubuntu@ubuntu:~$ ethtool -i eth0
driver: igb

supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: no
ubuntu@ubuntu:~$ lspci | grep Ethernet
