I had rare lockups using lidsuspend, which I couldn't track down nor even
properly report (laptop close to meltdown, X display frozen, no ddb,
power reset mandatory).
I have no visible change with this diff, except that I can't reproduce
those lockups (yet?). X display, apm(8), battery led, sysctl, zzz, ZZZ
everyone's happy including me.
