There has been rumors about the omission of the necessary chips to pull this off from being pulled from the CELL based machine - the PS2 has the original MIPS R3300a processor in there actually for PS1 playback.
Oh, and if you're still thinking I'm anti-Sony... I totally forgot. I'm the writer of the original Playstation FAQ way back in 1994.
