Really, the three hyperlinks are on the AMD64 die and they get coded to be coherent or not (I/O) based on what market the processor is selected for.

It is highly unlikely that random yield problems are the limit for the number of coherent hyperlinks on a given CPU.

Or in other words: if AMD wants to give AM2 CPUs a coherent hyperlink there is is nothing keeping them from doing so.
umm I believe we have already covered this.
ALL AM2 cpus DO have a coherent Hypertransport link
The main debate was if they had two like 2P setups and their associated processors
