What is the hack in question?
Also, please note that there were generalized issues with s2s to Google
Talk a while back, caused by some modifications on the Google side. Most
or all of those have been fixed by Google. Are there still problems
between djabberd installations and Google Talk?

As far as I can tell -- yes. If I am connected to google talk, and I try
and add as a contact someone on my DJabberd server, then the dialback
fails. For me, this is quite reproducible.
It appears that google sends a 'not-authorized' in response to DJabberd
sending the '<stream:features></stream:features>' stanza. Indeed, from a
packet capture, this looks as though it is exactly what is happening.
The packet flow is:
