Fascinating. I tried this, and it makes things even worse. Now the
laptop wakes up and hangs instantly; even the power button doesn't do a
controlled shutdown as it did without this option, and not even the
partial X screen is redrawn. I guess this tells me the problem is
associated with my graphics card. Maybe that will be of some help when I
learn more about how this works.
