Comment # 5 on bug 70207 from David Heidelberger (okias)

so bringing screen back fails somewhere on HW level?

in console:
  * driver set output=on, hw=on
  * result: output=on and hw=off stay
in X.org:
  * driver set output=on, hw=on
  * result: output=on and hw=on thanks to ? (some delay needed to resurrect
lvds? or trigger additional register?)
