[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.
