Alright, here's the full 'dmesg' output from when I loaded the kernel module:

As soon as those NDIS ERRORs start, the connection seems to die.

I think I edited if_ndis.c in the correct place and had it output what
I think you wanted to see...  Here's the diff, so please let me know if
I grabbed the wrong information, or did it at the wrong place.  If I
did it correctly, it looks like config.nc_dsconfig is 0.
