Is this still an issue for you? I am experiencing very similar symptoms (likely the same cause) with my Intel card. Same messages in /var/log/messages. The link just goes up/down constantly.
I can trace it going up and down with repeated calls to ethtool eth0 and watching the "Link detected" line cycle from yes to no with varying intervals. If I force 10 Mbps and turn auto-negotiation off (ethtool -s eth0 speed 10 duplex full autoneg off), the link becomes stable. But 10 Mbps on a 100 Mbps switch is not good enough. The strange thing is it was working fine for me for a while before suddenly running into this problem. Since then, I haven't been able to get a stable network connection. I booted the Dapper live CD and the same problem exists. I don't think this is unique to Gutsy.
