Intel Turbo Memory, aka Robson

There is complete silence on LKML and everywhere apparently about how
to use the Flash drive known as Turbo Memory in Linux.

This stuff is a flash connected to the PCI bus which Vista seems ale
to use to store frequently accessed data, so it bypasses the hard
disk, thus saving time. It's present on modern laptops, and is coming
to the desktop too.

I was wondering if anybody and better info than I, as I would be
interested in using it to save hibernation images and such, to speed
up restore time...

Nothing in the logs though...


P.S.: for those interested, here is a sudo lspci -vv:
