there's quite precise speculation on 3560 / 3750 buffer size here: http://www.gossamer-threads.com/lists/cisco/nsp/109456 > 0.75MB of ingress buffering is dynamically divided into port > buffers/queues, 2 of which are user-configurable.

So, the 4900 has 16M shared port buffers, the me3800x has 256 megs, and so on. As you note, good luck looking for any mention of the 2960 / 3560 / 3750 range buffers.
