Might be cool, yet I think SolidStateDisk drives will negate the
usefulness of such an idea. They are getting very fast. Sure, not as
fast as accessing RAM, BUT you have to first copy your OS image from
disc or HD before you can run it in RAM. This takes time.

I use a small SSD for my root, while /home /srv and other things are
mounted on a HD. I cold boot into KDE in a matter of seconds. BIOS test
and grub menu are the bottlenecks now.
