Help on built-in function bin in module builtins:

bin(...)
     bin(number) -> string

     Return the binary representation of an integer or long integer.

Manual
bin(x)
Convert an integer number to a binary string. The result is a valid 
Python expression. If x is not a Python int object, it has to define an 
__index__() method that returns an integer.

You can file a doc bug for whatever is missing in 2.6.  You might check 
other 3.0 builtins that were backported.
