Unfortunately I don't know (as this was a new hardware setup). Since it was a while ago and no-one seemed to have any ideas, I fixed the problem by changing to an e1000 (which had no further issues).
I've still got the offending hardware though, so it may be possible to throw some older distros at it to test.
