We have couple of these at our Tokyo office.
Here has the promotion video of the product.
Actually it is the same Cell BE machine which was demonstrated at 
SIGGRAPH last year.

It is bare-metal, no hypervisor like PS3. The kernel is almost identical 
with IBM Cell Blades.

It comes with RSX binary driver supplied by nVidia. It is not frame 
buffer like PS3; it has 3D acceleration capability.

The South bridge chip is the same with Toshiba Celleb and QS20 and do 
not have axonram.

It only comes with YDL but since the kernel is almost identical with 
QS2X series it should not be difficult to run Fedora.
