Please ignore this about nonvs. nonvs has nothing to do with the
suspend/resume problem on this laptop.

Instead it seems to involve reboots, which is crazy. From a cold
power-on start, suspend resume will always fail. But if the laptop is
rebooted first, suspend and resume appear to work. What the heck? I have
no clue how to debug this.

So now it appears that everything I ever tried to fix this only seemed
to work because I rebooted after changing GRUB or module options.
