I'm sorry this won't be much help but I finally gave up on my nvnet
card. The only distro that actually found it was debian. I tried all the
drivers from nvidia in fedora and RH9 but never got it to work right. It would work
fine for a few seconds then just kill my system for a few seconds this
went on and on anytime I was transferring files over the network, Any
substantial network traffic just killed me.
Take my advice and add another card if you can.
