if you have a unix or linux machine on the subnet you could try running
arpwatch or tcpdump to try and get an arp address for the switch, if you did
manage to get one then you could "assign" it an ip with arp by doing 

arp -s (arp-address) 192.168.0.1 (or whatever ip is free on that subnet) 

(or similar) which means you could telnet or www to the switch from that box 
and give it a real ip address. Make sure you delete the entry you added to 
the arp table too its not a good thing to leave in.

What you are actually doing is telling your machine that a device at an arp
address has a specific ip address, this means the device will get sent the ip
packet directly without any arp negotiation having to be done. Anyhow I am
guessing that you took the train by now as its a bit after you originally
asked.
