The playstation site for Europe has a list of compatible games here:

Hope this helps. Note that not all titles on the list are fully compatible, this is indicated by one to three 'blocks' where three is a-ok and one is 'has issues' ;)
Edit: Lucky us the website is not functioning properly at the moment and only lists a tiny amount of games where I know there are many more :-S
