I just bought an Uther from Sean Fahey, and am having some issues, so
I'm asking for assistance here before I send the card back for another
one...

My system is a ROM 3 GS, with no upgrades (other than the Uther.)

I attempted to use ADTPro over ethernet, that didn't work, so I then
moved onto Contiki.
With ADTPro setting the software to match the actual slot it is in should do the trick. I am assuming you already had a disket with the ADTPro client already on it? Bootstrap is not supported with ethernet. 



Contiki couldn't get an IP address. And, if I gave it a static IP, it
couldn't do anything.
If the software was communicating with the card, either one of those should have worked. The DHCP application or static assignment as long as the slot matched the one it is in and "your card" is set for any slot. (slot 3 and 4 are exceptions to that rule. They can be left at "Built-in Text Display" and "Mouse") 



I've tried the card in slot 2 (Your Card), 3 (Built-In Text Display),
5 (Your Card), and 7 (Your Card).

The router (a Linksys WRT54G v7) and the Uther's link lights light up,
but the Uther doesn't show up in the MAC list on the router.
The software has to initialize the MAC address even thought the chip will respond to broadcasts as you have found out. Thats why no MAC address on the Linksys (yet). 



Broadcast pinging the subnet that the Uther is on causes the activity
light to blink.
This shows at least the card is alive and functioning from a base Ethernet perspective ... we just can't communicate from the host to the chip to set it up or process any packets. 

DHCP requests also cause activity light blinking.
So you are saying then that when you use Contiki and you start the DHCP applet that you see the activity light blink? That would mean to me that the software can talk to the chip. 




I've also tried plugging it directly into my ThinkPad, which has an
autosensing ethernet port. (No crossover cables necessary. :)) The
ThinkPad saw the card, and connected to it at 10 megabit half duplex,
but with manual IPs set, nothing happened.


What software where you trying to use at that point?

 I also fired up Wireshark,

and attempted to get a DHCP address on the GS. Nothing.
That should have at least shown the broadcast looking for a DHCP server .. seems odd that it would cause the link light to blink but no packets captured.
You probably already know that a simple 10Mbps hub is a requirement if you plan on doing any ethernet development in order to capture all packets. 



The cable is known good - I linked my ThinkPad to it on one end, and
to the router on the other, and was immediately able to get online.


Oh, and something that I forgot to mention... Sean said that he had
tested the card with Contiki before he sent it to me. So, my GS is
what I'm suspecting the most.

if you want to contact me by email - we can setup a time tomorrow and I can help you over one of the IM's.
I need to check back in my notes but we should also be able to poke a few values to some of the registers and read them back - that should tell us if we can communicate with the chip or not.
I also have a couple of test programs based on IP65 that we can use to try and verify the connection as well.
The only time a IIgs hasn't worked for me was when it kept losing the slot settings when I turned it off as the battery was suspect. I would plug in the card (slot 2), turn it on, set up the slot to the right setting, warm start the machine, the card would work. I would turn it off and swap in a the next card to test and then the next card would not work. This drove me nuts for a awhile till I went back in and found out the slot had reverted back to it's default (Modem or printer - I can recall which now) - Probably not your problem but thats all I have right now.
