Yes.  Sorry, we don't know how to make this NIC work right
with PM resumes.  I think Donald hinted that he was getting
a datasheet, so I'm watching his ftp server with interest.

If you grab the latest driver from 2.4.2-ac15 or
http://www.uow.edu.au/~andrewm/linux/#3c59x-2.3 then
you'll find the situation improved - if you
do

	rmmod 3c59x
	modprobe 3c59x

in your power management resume scripts then things
should be happy.

>From memory, this means creating an 
/etc/sysconfig/apm-scripts/apmcontinue which looks like this:

#!/bin/sh
rmmod 3c59x
modprobe 3c59x
ifup eth0

but it's been a while since I fiddled with this.  Please
let us know the outcome - if it works I'll update the docs.

Thanks.
