Please see the mail from this list dated Feb 8 and titled "changing focus
location for screen readers". This mail contains a pretty good discussion of
the matter at hand. As far as tabindex is concerned, ie8 and firefox
supports it on any element, and to the best of my recollection ie7 also
does. ie6 I am not sure (though it doesn't support aria this may have been a
proprietary thing back then).
