Comment(by cjb):

 > We currently wait *twenty minutes* before we do this, though we dim the
 backlight after a single minute.

 No, this isn't right.  Either you have power management turned on, in
 which case the backlight dims after a minute and then you suspend and then
 nothing further happens to the screen, or you have power management turned
 off, in which case the screen turns off but never dims.

 I haven't been working on the case where power management's turned off; I
 tend to think that people have no desire to save power in that situation.
 We could probably stand to lower these timeouts, though.
