I've run a sustained 10Mbps tx & rx on 8 ports (2 of the Dlink 4-port NICs) for over 24 hours on a 2.4.7 kernel. I was not using bonding though. I'm guessing you're seeing lots of carrier errors, as the tulip driver used to be very bad at...uh..working. Try a 2.4.6 kernel or better and I bet your problem goes away...
