This seems to violate the RDFa spec (and stomps all over every vocabulary 
in XML).

I'm surprised you're ok with this. :-)

Yahoo seems to be seeing triples, and detecting one game:

   http://developer.search.yahoo.com/help/objectfinder?url=hixie.ch%2Fwww%2Ftests%2Fadhoc%2Frdfa%2F002.xml

What were you testing that indicated it didn't see triples?

Note that the page above breaks; Yahoo doesn't show the button to show the 
RDF at all.

This test seems to work for me:

  http://developer.search.yahoo.com/help/objectfinder?url=hixie.ch%2Fwww%2Ftests%2Fadhoc%2Frdfa%2F003.xml

They seem to get picked up for me:

   http://developer.search.yahoo.com/help/objectfinder?url=hixie.ch%2Fwww%2Ftests%2Fadhoc%2Frdfa%2F004.xml

They get handled differently than 003.xml, though, which is a bug since 
the RDF in both cases is equivalent.
