You might have better luck if you 'google' for check CiteSeer for both the old name Hammer as well as the new Opteron and AMD64 as I think there more more disclosures under the code name than the released one.
Couple of basic places to get started:
Nice write-up by Chip-Architect on the Opteron Core at Understanding the detailed Architecture of AMD's 64 bit Core
(See section 3.3)
Some of the MPF documentation on Hammer from the old days: 2001 Hammer MPF
Can also check some of the architecture manuals, like AMD64 Architecture Vol2 System Programming

Not sure any of them will give you easy read of the replacement algorithim itself -- But there is a good description of the TLB function and maybe you can infer the replacement algorithim.
