I do not think its is purely a WM (I am assuming this means window manager)
issue. As I have mentioned before, the flicker occurs whether X is started or
not. It is true that there is dramatically less flickering when X is not
started, but on kernels that work, there is no flickering in either case. This
leads me to believe that if the flickering without a WM is eliminated, then the
flickering with one will be as well, though obviously this it not certain.

As for bisection, I find that the problem occurs between 3.9 and 3.10 and not
3.8 and 3.9 as Thomas claims. I bisected it to be introduced by commit
3600836585e3fdef0a1410d63fe5ce4015007aac.
