Warmth of objects in DB buffer cache?

Querying v$bh I know which objects are in my default DB buffer cache at a given point in time. I want to put the most frequently-accessed objects into a new "keep" buffer cache. How can I tell which of the objects are the frequently accessed ones?

The only way I can think of is to query v$bh at regular intervals and see which objects consistently show up there, therefore are not getting aged out. However I would have thought that there would be a statistic to tell me how many times each buffer had been hit since it was originally read from disk - is there any such?

Thanks in advance,
 James
