never got to see that message. I saw the diff to previous version, and did
boot into verbose mode (dmesg attached). there were just the belkin
gigabit nic on boot. after, the linksys USB200M:

and the other gigabit:

and never got to see the EEPROM message.

I'm trying this, usb nic out of bridge, its own IP, tcpdump and iperf. few
minutes and no problem so far. let's see in some time. when bridging for
my DSL, it got something around 1~3Mbps of traffic. and in less then a
night (8 hours) the usb nic would say goodbye ...

thanks again,
