Cufon replaces the text with an image, but the text is hidden there for reading from the screen and accessibility. You will see this if you check the element, so that it is in the DOM. You might want to change your CSS so that it is located above or below the cufon text, perhaps with an opacity of 0.01 so that it is not visible, but is selected.
I have not tried this myself, but this is the first thing I tried in this situation :)
Sort of:
cufon cufontext { display: inline-block !important; height: 16px; overflow: visible; text-indent: 0; width: auto; font-size: 16px; opacity: 0.1; position: relative; top: -16px; }
