and I did.  Eliminating typos on 'insmod netconsole.o ...' helps.  :)

Here's 3c59x.c patched for netconsole (HAVE_POLL_CONTROLLER).

Ingo, you _are_ planning to use most or all of Andreas's patches,
aren't you?

I'm interested in using netconsole early (during boot).
Any problems doing that, other than getting module parameters
to it?  I can fix that part.
