Here's what I've found so far: First, the 82547EI will fail due to Invalid Mac Address, so I guess you hacked around this problem yourself? I had someone here test all legacy adapters for this problem and I was told nothing else was exhibiting it besides the 82542, obviously this is false :) In any case I will be making an official patch to fix that problem soon. Second, once I had the device working I do indeed see substandard performance, I am continuing to debug, but wanted you to know that I have reproduced this.
