During some large bisects on previous kernels, I've noticed it make a
switch from ttyS2->ttyS4 before. In other words, this might have
restored some *old* behavior inadvertently.

The annoying thing is that these assignments *do* keep swapping around.
I don't really care whether or not we revert this, only that we pick
one order and stick with it.
