What about the TITLE attribute in the AREA element? Might that not be used
as a replacement for ALT?

It specifies an optional advisory title for an element, as for other
elements. It could be an auxiliary hint, or something.

That's not its job at all. And you cannot rely on TITLE rendering
in principle (it's just advisory, by definition) or in practice
(implementations vary from awful to poor).
The short story of image maps is:
1. Don't use them. Use links, Luke.
2. Well, if you have something that is inherently visual
and two-dimensional, like a geographic map, things
get different. Then specify ALT attributes as a matter
of principle but _also_ write an alternative set of textual
links, if possible. Maybe on a separate linked page.
The long story is "Tooltips and alt texts for image maps" at
