Note that here you assign self.val to be the object itself.  Are you
sure you didn't mean "self.val = init_val"?

Instead of an integer, you return the current class instance as set up
in __init__.  The __int__ method ought to return an integer.

And this will be infinite recursion, since long(<obj>) will try to
call the __long__ method on <obj> so you're just recursing on the
__long__ method.

You can see this more clearly with:

    >>> cat = myclass(0x55, 32, my_reg)
    >>> int(cat)
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    TypeError: __int__ returned non-int (type myclass)
    >>>

I won't post the traceback for long(cat), as it's, well, "long" ...
