Bug Description
I have a Lenovo T61 (and another Lenovo T61p) that has Intel Turbo Memory in it. I'm not suggesting any approach as to how to use the memory - I just want access to it as a block device so I can do something with it.
There is a Brainstorm entry about using Turbo Memory in a fashion similar to ReadyBoost: http://
Here's the relevant output form lspci -vv:

I can't find any sign that there is any kernel support for this yet
