Damn, i just gave Zork a shot with a keyboard plugged in, no luck. I didn't really expect it but, worth a shot. The ingame virtual keyboard would be hell with games like Zork.
Anyone with an official ps3 keyboard wanna give it a shot? It's unlikely, it's not listed as a feature and i haven't looked at the source yet so i don't know, but it may work...
