[PS3] Play Black ops with keyboard and mouse?

Hey :): I have a question. I know we can plug it in, browse the internet, type and stuff but Is it possible to play COD on the ps3 with a keyboard and mouse? I do alright with the sixasis but ive been wanting to try the keyboard/mouse. and I cant play Black ops on the PC. My computer sucks, it cant even run cod 4 o-o

Thanks.

Even if you get it to work, the keys will be all messed up I think, as you can't configure them on PS3.

well this sucks o-o Yay Sixaxis

That would create a unfair advantage now wouldn't it?

I've always wondered this didn't think it would be possible, although if it was my K/D ratio would be even better than it already is.
