I think it's time to have that discussion on the list :)

After your commit 23ffccd5d7c9a88d479f82043ff1b6efe938cc6a, which 
changed forest, domain and domain controller functionality levels to 
2008, I cannot join a W2K8 server to an S4 domain.  After reverting that 
commit, I am again able to join a W2K8 server to an S4 domain.

I am attaching the relevant section of my samba.log containing details 
from when the domain join fails.
