Michael,

Thanks for the info.  Like I said in previous e-mail I've not tested
modules nor do I use them unless absolutely necessary.

The question is who is the maintainer of the NE2K ISAPNP interface?
Is this an NE2k maintainer issue or an ISAPNP issue or a "you have
the hdwr" you fix it thingy?

I can hack on ne2k but don't want to spend time on it if someone else
already is or has a better solution or possibly colliding with ISAPNP
development again as did my last patches sent to Linus.

Martin
