Hiding text *from* screen-readers

I have a page (http://www.polimi.it) with a news ticker on it. I want
to have all the ticker's news read by a screen reader, which is easy
enough using the off-left trick, but also to have to ticker's tag
(#esterno) ignored by the screen reader *and* shown by the browser.

Which screen readers will properly honor

<style media="screen">
#esterno { position: absolute; }
</style>
<style media="aural">
#esterno { display: none; }
</style>

and not botch when the HTML changes under the hood? And which
browsers will simply hide the ticker because they use the aural style
sheet as well?

I need to support IE5, IE6, and recent Geckos. As for the screen
readers, JAWS is strictly necessary, but others would be good.

Thanks,

Paolo

Just FYI, since all the news items are to be included in the HTML for
screen readers, instead of hiding the items using the off-left trick,
I modified the ticker script so that it only modifies the positioning
of the items. Effectively, I use the off-left trick to hide all the
news items but the ones that are currently scrolling.
