Actually there is no such thing as a ATmega256 now, they changed the 
nomenclature yet again, as you can find by searching the net for the 
ATmega2561.  There are a few variations in package and memory size, per
the public information from the seminar last year.

AVR097: Migration between ATmega128 and ATmega2561 (6 pages, revision A, 
updated 11/04) 

"ATmega128 and ATmega2561 are designed to be a pin and functionality 
compatible sub family. This application note points out the differences to be 
aware of when porting code between the devices."

http://www.atmel.ru/Disks/AVR%20Technical%20Library/appnotes/pdf/AVR097.pdf

From other public information on the net, such AVR Studio 4.11 release notes 
we know there is a ATmega2560.  We know from AVR097 that the 2561 is a 64-pin
part, it can be deduced from the seminar material that the 2560 is the 100-pin 
part.  The other information has not turned up in what is publicly available 
yet.
