I did see something unpleasant with xrandr(1), however. I have dual external monitors attached, which I have a login script set the resolution properly. With my resolution set to 3840x1080, X is unusable on resume. (The screen is fuzzy, but the machine does not crash.) Without changing the resolution before suspend, X works properly at resume.
