Thanks for posting this.
I am a little suprised at some of the results especially with
NAPI + packet mmap. 
I have had no problem at all handling wire rate 100mbps with 
tulip-NAPI in 2.4.x using packet mmap on a p3 or maybe it was a p2; This
is zero drops at 148.8Kpps.
Jason Lunz actually seemed to have been doing more work on this and
e1000 - he could provide better perfomance numbers.
It should also be noted that infact packet mmap already uses rings.

cheers,
