Incidentally, I also tried the 2.6.33.2 kernel with 
CONFIG_FORCEDETH_NAPI set to "y" to see if that made a difference.

It doesn't - further testing over the weekend saw 6 of 45 machines drop 
off the network with this problem. Nothing in dmesg or system logs. 
Happy to run more tests if someone can advise on what should be run.
