I have good news and bad news.  The good news is that I can reproduce 
this problem 100% under Panther.

The bad news is that the problem seems to be a bug in Apple's DHCP 
client.  It is failing to remove the IP address from the interface when 
the DHCP release fails (interestingly, it does remove autoconfigured IP 
& IPv6 addresses, so this is definitely DHCP-specific).  The reason I 
hadn't noticed it myself is that my DHCP server hands out addresses 
based on the DHCP client ID, so it usually gives me the same IP address 
for a particular machine instead of a different one on each request.

The DHCP release happens after our driver unloads, so we can't simply 
"fake" a successful transmit for the DHCP release.  We'll pull over the 
current Darwin sources and see what we can do to work around the 
problem.  I can't promise a fix will make it into 1.0.3, but as soon as 
we have a fix we'll issue it as a bug fix release.  If we can't work 
around it, we'll open an incident with Apple and suggest a bug fix on 
their end.

Thanks again for the detailed bug report.
