I can't bring myself to trust Sony anymore

Wait, can I actually go right now and insert a PS1 disc into my sister's PS3 and play it!? Please tell me before my feet begin dancing of joy.
But wait, if so then PS1 games are region coded right :( Damn, I wanna play Valkyrie Profile T_T

 

Edit:

It's an 80GB PS3
