Comment(by mikus):

 Unfortunately the hardware on my XO-1.5 B2 is supposed to not handle
 suspend well - so I disable suspend on the XO-1.5.  However, with the way
 I have my systems set up, suspend on even an XO-1 (if enabled) will often
 take place *despite* a long-running process (such as a 700 MB download)
 still being active.

 My bypass is to also run my XO-1s with suspend usually deactivated.  But
 when I *do* have suspend enabled, I definitely WANT warning ahead of time
 (before the system actually "sleeps" the cpu).  Then if I don't want the
 cpu to go to sleep, the dimming of the screen gives me time to manually
 intevene (typically, I press 'shift') -- and aviod that will-soon-happen
 suspend.

 [[BR]]My point is that, although someone would not want the screen to dim
 who would want the system to suspend (and save electricity) between
 sentences of foreground input -- someone else who was concerned about
 suspend interrupting a background process might well want to see the
 screen dim before suspending.

 My personal preference would be to keep "screen dimming" -- but to have an
 explanation in the Release Notes,  telling each of those users how to
 specify the kind of dimming behavior he wants.
