This question really isn't very clear to me, so the below may be
completely off the mark.

First of all, updateSome()'s signature is 

   updateSome(cls, adict, *args, **fieldData)

while new's signature is

   new(cls, **fieldData)

I take it that you are overriding both updateSome and new and want to
reuse the code that modifies the dictionary going in both cases.
Let's say that the method that modifies the dictionary is X.  Isn't
the following good enough?

   @classmethod
   def new(cls, **fieldData):
       return BaseClass.new(**X(fieldData))

   @classmethod
   def updateSome(cls, adict, *args, **fieldData):
       return BaseClass.updateSome(X(adict), *args, **fieldData)

(I'm a little uncertain how to use super() in this situation, so I'm
just punting on it.)

If my guess as to what you might have meant wasn't good enough, please
clarify.

Cheers,
