Geert Uytterhoeven 310d8c1112 [PATCH] ps3: Virtual Frame Buffer Driver
Add the PS3 Virtual Frame Buffer Driver.

As the actual graphics hardware cannot be accessed directly by Linux, ps3fb
uses a virtual frame buffer in main memory.  The actual screen image is copied
to graphics memory by the GPU on every vertical blank, by making a hypervisor
call.
