What about using setattr?

    for name, value in kwargs.items():
        if name in ('a', 'list', 'of', 'valid', 'keywords'):
           setattr(self, name, value)
        else:
           raise ValueError, "Unrecognized keyword " + name

I'd probably turn the list of valid keywords into another dictionary to
make it easy to specify default values for all the parameters as well.
