Problems with irc because of tor?

[Praedor Atrebates <praedor@xxxxxxxxx>]

I have been fighting to get tor-0.2.1.7-alpha working on my system for a while 
and finally appear to have it working now.  Now I find that trying to connect 
to IRC servers fails:

[15:06] [Info] Trying to reconnect to irc.freenode.org in 20 seconds.
[15:06] [Info] Looking for server irc.freenode.org:6667...
[15:06] [Info] Server found, connecting...
[15:06] [Info] Connected; logging in...

[15:06] [Notice] -- *** Couldn't look up your hostname
[15:06] [Notice] -- *** No identd (auth) response
[15:06] [Notice] -zelazny.freenode.net- *** Banned:  Tor freenode is hidden-

(2008/11/18 21.17)
[15:06] [error]  Closing Link: 127.0.0.1 (Banned)

Why does running tor suddenly cause me to be unable to connect to freenode?  I 
am NOT running a torified irc client.  Also, where's the address 127.0.0.1 
coming from?  Why is my REAL IP address now invisible (apparently) and tor 
causing sites to think I am trying to use the <illegal> localhost IP?
