The current X code is not sensitive to all PM events: last  I checked
only APM.  However, currently the code is such that a suspend event
automatically switches to a text VT and resume switches back.  It makes
sense to have this kind of code in the VT switch handling, since an
application can do strange things to the video whilst we're switched
away from X, so technically, X should never assume any kind of state
when it switches back.
