Nobody, I am also interesting in looking at this code, with the goal of 
getting networking to work in a VirtualBox client.  (My main machine is 
AMD-based, so I am interested in that also, but I like to do most of my 
experimenting in a VM.)

Unfortunately, I don't have much free time at the moment, but I can try 
to assist your efforts as much as I can.  I haven't worked on 
driver-level code in years, but I don't mind shaking off the rust for a 
good cause.  ;^)

If you post your discoveries / observations on this ML (or elsewhere, as 
appropriate), I will do the same.
