The Congo platform is already out, as much as I know. The basic is the new "AMD Athlon/Turion Neo X2" CPU. This is basically a K8/10 mixture, like the old Turion X2 were and still in 65nm, as you also can see at AMDs roadmap: Congo = Consensus:
There's e.g. the HP Pavilion dm3-1000 with this kind of processor at the moment.
Also, Lenovo is planning to come out with a ThinkPad X100e and ThinkPad Edge including this kind of processors.
I believe the dv2z is available as Yokon or Congo platform. But it's probably easier to find them via their new/other? name: dv2-1110eg and dv2-1120eg.
