kpf,

They are releasing some of the parts as 1.4GHz Opterons.

Okay, they may be capable of more than that, but there's nothing to suggest it's a particularly narrow range, when the output is being used in parts that range from 1.4GHz to 2.2 GHz, right?

FX would still be necessary, for certain benchmarks:

Higher core speed is not equivalent to doubling the memory bandwidth (even if this double bandwidth has slightly higher latency).

I'm not sure why many assume that Opteron and Athlon64 have the same die. Of course, they have the same core, but the die has to be different to enable non-registered memory. Otherwise, why else would the FX require registered memory? For that reason, it wouldn't make any sense to say that A64 is binning alot of sub-2ghz chips which are being sold as Opterons. Either it's not binning that low or AMD is rejecting the slow ones.
