Yes it the same machine.

I'm having the same problem on the same machine. Peter's
original patch fixed it once as far as I know. I have patched
the currently kernel with Peter's original patch though have
had no success bringing the interface up.

Thats why I started looking at older drivers since they
play nicely with the switch.

Peter is currently on holidays, and I am using the machine
for benchmarking and assisting with solving this problem. 

I should of let you know to avoid the confusion.
