I made the changes to smwfParseAttributesAfterTidyCallback() that you suggested. Below is my patch in case anyone else is interested. Not sure if I considered all the ramification of this change and I've only just started to use it, so proceed with caution if you decide to use it as well! The revision number is from my repository, so don't count on it for the version used. I made this change against version 0.7.

SMW 0.7 doesn't offer any way to control the appearance of attributes in
text.  You see the original value or the alternate text after the '|.
It seems the philosophy of SMW is to retain the original text the author
wrote inline, and only modify the property's appearance in tooltips, the
factbox, and inline queries.

However, by modifying the PHP code in smwfParserAfterTidyHook() or
smwfParseAttributesAfterTidyCallback() you could change the steps that
rewrite the HTML to add the tooltip, and do something else.
