WAI-ARIA editor and VoiceOver developer James Craig's personal opinion:
http://lists.w3.org/Archives/Public/wai-xtech/2011May/0013.html

Excerpt:

]]
In my opinion, the presentation state would only apply if one of the following
were true:

 the author explicitly provided a role of presentation on the img tag, <img
role="presentation">
 the host language labeling mechanism (in this case @alt) equaled an empty
string, *AND* the ARIA text alternative computation [1] equaled an empty
string.

[ snip ]

1. ARIA text alternative computation:

My comment: 

1) The ARIA text alternative computation does count in the @title attribute.
2) James's comment supports the view I have expressed by filing this bug.
