The "alpha" parameter is just a Boolean that identifies whether or not
alpha is present in the first parameter.  So, to get the effect you
asked for, you'd want:
    HexColor( 0x80ffffff, alpha=True )

The root of the problem is one missing set of parens around the
(val>>24)&0xff term, which your patch adequately corrects.
