To me, it looks less like a hand coded serp, and more like they gave a group of sites more bonus points if they contained part of the query string.

I think I've seen these called authority sites somewhere... Could it be that Yahoo is part way into a switch to contextual based search and they're setting up some lexical reference points?

Nah! Has to be hard coding. ;-)
