(Maureen:) I'm not sure if you're wondering about direct theoretical geneologies or about inherent affinities between ideas.
Think I'll pass on the pomo question because I'm abstaining now from generalizations about post-anything on the list (as opposed to particular theorists). It's too charged!
I think you'd like an essay by your erstwhile classmate, wildboy Taussig, called "Maleficium: State Fetishism" (in _The Nervous System_). The bulk of the essay is his meditation on what it is that Durkheim is tapping into, in _Elementary Forms of Religious Life_. The badboy Marxist makes almost no references to Marx in the essay. (Though, getting back to the Hegel theme: he does mention how Durkheim in effect sociologizes Kant's a priori categories, echoing what others say Marx did with Hegel's Subject.)
Don't be fooled by the typical Taussig theatrics, I think it's one of the profounder things he's written. It's also a visceral tour through a part of the woods that contemplates classification (and its relation to materiality/signification questions) differently than Marx. Which isn't at all to say the parts of the woods don't connect!
