I know it'd likely be more cost effective to buy a new system with AMD-V or Intel VT-x, but to prove it, I need to know if there are any 939 socket chips that feature AMD-V and if so what they are. This would allow one to run a windows server guest under Xen.
Update
This question will likely be of little use three years on, when you can't even reliably buy 393 socket chips. But I thought I'd mention that yes, the context was that I owned a socket 939 system and wanted to start running linux primarily with a Xen guest hosted Windows. For that I needed AMD-V, but it language on AMD's site was that all their chps support it, which it's clear from these answers that "ALL" wasn't including 939 chips.

There are none. The AMD-V feature was introduced on Athlon processors that used Socket AM2 (the successor of Socket 939) and on Opterons that used Socket AM2 and Socket F.
