Dont get your hopes on that unfortunately..

Sony like was all over Linux on the PS3 and on the PS2 but later on they decided to remove the OtherOS feature on the PS3 and on the PS2 they stopped supporting it according to there official DEV site.

I actually bought a PS3 for Linux use since it claimed to be "POWERFUL" but i didnt realized Sony removed the feature before i had the chance to even bother to use it at all so i kept it for like gaming nothing really appealed to me at all the thing just dat there doing nothing and just got rid of the thing.

Linux on a PS system NEVER GOING TO HAPPEN.. unfortunately
