I'd be surprised if they don't have custom graphics hardware, of some sort, in there - I imagine the last thing Sony wants is to commoditise themselves by providing the same hardware platform as normal Android phones. Even if they don't have custom hardware, I'd be shocked if they didn't have some sort of silicon DRM to stop the software running elsewhere.
