I would imagine, that ideally for multithreaded tasks you would want the same module due to the shared L2, but for separate tasks you would want different modules due to the performance loss from sharing components
It was answered on the blog, that the shared L2 Cache wouldn't really help.

As for the Multitasking, I suspect it will work like Intels HT. As far as I'm aware, that doesn't cripple 1 core only, but spreads it out amongst the other cores first and foremost.
