fix screendump (Stefano Stabellini)

Browse source 
this patch fixes the screendump functionality that was recently broken;
it must be applied *after* PATCH 5, 6 and 7 of the original displaystate
change patch series.
In fact the other patches make much easier to solve the screendump
problem because they make the console switching mechanism more robust.
