Heh, oops. The used-to-work -21 kernel hangs the same way. It turns out that the configuration change that caused this bug is the presence of a uSD card in the card reader. Take it out and both -21 and scien boot fine (still have to try scien+i915bri, but I'm sure that's fine).
Apologies for the confusion. I'll file a separate bug.
