Daniel, you're awsome! :-)
I've tested it too and it works great with the OSKit from Savannah.
Even when I had applied my own upgrade patches to get my NIC running
the kernel ran smoothly, this far at least.

I did a very small non-scientifict test pinging the box with no load
whatsoever. Below are the results, first is against GNUmach1 and
the last, GNUmach2, including your patches. (There are no other boxen
on my network to disrupt traffic)
GNUmach1:

GNUmach2 (OSKit-Mach):

When I flood ping GNUmach2 I get 1% loss and no package loss with
GNUmach1. Maybe we can spur some interest in tuning these numbers
a bit?
