This sounds exactly like what I saw on a 500AU a while ago. As long as
the SRM was in control the builtin tlp-card worked fine but as soon as
the NetBSD boot block took over nothing ever left the card. I don't
remember the details but I googled a little on netbsd.org and draw the
conclusion that it migh be some problem with the PHY.

I also tried to boot from a floppy and run ifconfig manually but was
still unable to get it to work, tried all combinations of media and
options, tried different hubs / switches. Nothing seemed to help. Have
you tried that?

Finally I stuck a cheap tlp-clone into the box and it worked without
problems. I never got the time to investigate further (as usual :)...

Best regards,
