To my knowledge, there isn't a "Radeon 9600 IGP". Therefore shared memory is unlikely. The only place that listed the notebook with shared memory is Amazon anyways. NewEgg and Buy.com both lists the notebook with Radeon 9600 64mb Dedicated.
The Mobile Sempron is basically the K8, or Athalon64 core without the 64bit extension. It even has the memory controller.

Note the Mobile Sempron is based on the K8 core. Even at 2600+. Can anyone correct me if I am wrong?
As far as I know, the notebook comes with 1 stick of 256mb PC2700. I am waiting for my local Sam's to carry one so I can play with one before getting it.
