When we speak of sparc64 we simply mean the 64-bit Sparc userland ABI. When we say v9 we mean sparc 32-bit ABI plus availability of the Sparc v9 instructions. Someone inside Fujitsu at some point got the most recent Fujitsu chips working (they are very close, MMU/Cache programming wise, to UltraSPARC unlike the initial fujistu 64-bit sparcs) but they never submitted a final patch to me and all that stuff is pretty dead these days anyways :)
