sgolds re: socket 754 has enough pins to support a second memory controller

No need for supporting a second memory controller. There is only one on K8.
What is often referred to as "Dual DDR" is in fact single channel, but 128bit-wide instead of 64bit.

Just in case you are speculating about specs for Athlon64-launch: 64bit Channel. Confirmed yesterday by AMD Germany.

Confirmed as well: Current K8 Memory Controller is not capable to support DDR-2......But implementation of a modified Memory Controller for DDR2 "technically trivial."

However, no clarification given whether Socket 754 allows 128-bit channel technically:
....change memory decision if market requests... no roadmap for if or when ... cannot confirm socket-specification for 90nm-successor.
