Sony has put together a nicely-organized PS3 compatibility database, so all you PS3 owners can check to see whether or not your old PS1 and PS2 titles will work with your 60GB, Emotion Engine-equipped model, or the newer (or European) model without the Emotion Engine hardware.

It's a shame they took out the EE hardware, whose purpose was to deal with the backwards compatibility, but at least Sony's owning up to and detailing any problems you may have with your library of games.
