Hi Mike,
  I think I understand your problem better now, thanks.
As far as I remember, perhaps Roger and other EG members can correct me
here if I am wrong, the "disabledClass" and "enabledClass" on select tag
were meant to applied to options and not to the element itself because
if you are planning to use the same style class on all options then they
don't have to be repeated on every option.
   Coming back to your question, assume a scenerio where the two options
have different values for "disabledClass" which one would you apply on
"select" tag ? Thats one possible explanation for the current behavior.
In any case, I'll let Roger decide if it needs to be spec chande
although std. Renderkit docs don't discuss it in detail.

Regarding "disabled" being rendered on select tag, are you sure about it
? I have a test case where I see its not being rendered and I think its
because of the following code in MenuRenderer

// don't render disabled here, because it is dealt with in a
    // special fashin further down the callstack.
        Util.renderBooleanPassThruAttributes(writer, component,
                         new String [] {"disabled"});
