David & co, any ideas?

There are other reports of problems with 3.3.x kernels, there's a
report from Tim <timliette@woh.rr.com> which may be related (also
apparently working in 3.2, broken black screen in all 3.3.x).

Nick, I realize you had trouble with a bisection already, but it might
really be worth trying again. Do a

    git bisect visualize

and try to pick a good commit (avoding the problems you hit) when you
hit a problem, and then do

   git reset --hard <that-point>

to force bisection to try another place. That way you can sometimes
avoid the problem spots, and continue the bisection.
