James Craig touched this:
http://lists.w3.org/Archives/Public/wai-xtech/2011May/0040

His quote from ARIA: ''If an element with a role of presentation is focusable,
user agents MUST ignore the normal effect of the role and expose the element
with implicit native semantics, in order to ensure that the element is both
understandable and operable. ''

I did indeed not think about this when I suggested to use <a role=presentation
href=link >. 

HOWEVER, it is possible that ARIA should continue to permit role=presentation
on focusable elements, because:

* the ARIA spec text talks about 'the *normal* effect of the role'. For
example, what if a table cell of a presentational table has the tabindex
attribute set? It would be meaningless to treat that table cell as a
non-presentational table cell.

* note also that @role may take a list of several roles. I would thus suggest
that 
 <a role=presentation href=link > is equal to 
 <a role='presentation link' href=link>
