I just installed CentOS 5.0 on one machine here and
have a similar problem. I haven't changed the config
file from what was installed, and it looks pretty much
like the config in CentOS 4.5. 

I've got openssh-4.3p2-16.el5 on the CentOS 5.0
machine, and have tried to get X11 forwarding working
on connections from three machines with different os's
-- centos 4.5, ubuntu and Mac OS. 

ssh -v doesn't seem to say anything out of the
ordinary. After authentication, it says:

Entering interactive session.
Requesting X11 forwarding with authentication
spoofing.

Trying to open an emacs window without a -d argument,
I get a message about no address for localhost:6010.

Supplying the -d argument, I get 
Xlib: connection to "xxx:0" refused by server
Xlib: No protocol specified.
