Apparently 2008 R2 supports renaming domains.  You could join a 2008 R2 
DC, sync everything up, move your FSMO roles over, shut down your Samba 
DCs, rename the domain on the remaining Windows DC, then rejoin your Samba 
DCs as new DCs, move your FSMO roles back, and shut down your Windows DC.

I'm curious what would happen if you did an ldbedit and did a 
search/replace on the entire ldap database and changed every reference of 
the old domain to the new one.  Then restart the DC, and all member 
servers/workstations and see what happens.

Obviously, someone should test that in a lab first... it may well blow up. 
It's entirely possible the ldbedit would just fail, as it can be picky 
about changing certain things if they would conflict or cause errors...I'm 
not sure if it's possible to edit _everything_ in one go, even with 
--relax --cross-ncs.
