Bisection shows that the resume-from-ram failure is caused by
commit 987196fa82d4db52c407e8c9d5dec884ba602183

cpuidle take2: Core cpuidle infrastructure
Note that this is the patch which *fixed* resume-from-RAM prior to Thomas's
git-hrt merge. Now it breaks it!?!?!
Also, I'm seeing this, in mainline, when I do echo mem > /sys/power/state

Didn't appear to change anything. Bear in mind that e100 netconsole is a
bit busted across resume anyway, and the video display on this machine has
never ever survived resume-from-ram (but the X server can bring it back).
