You don't need to disable the normal touch screen actions to make footnote links work, you just need to make the link to the footnote large enough to activate it easily.
E.g. if your link is something like this then you might well have problems accurately touching the link at small font sizes:
Code:
css:
a.fn-link-decoration {color:blue;text-decoration:underline;}
xhtml:
<p>... Foo<sup><a class="fn-link-decoration" href="notes.xhtml#fn1" id="f1">1</a></sup>, bar, baz.
but if you do it like this it will look identical on the page but there will be a much larger target area to touch:
Code:
css:
sup.fn-decoration {color:blue;text-decoration:underline}
a.fn-link {color:inherit;text-decoration:inherit}
xhtml:
<p>... <a class="fn-link" href="notes.xhtml#fn1" id="f1">Foo<sup class="fn-decoration">1</sup>,</a> bar, baz.</p>
