I am almost sure that this has to do with the fact that I adapt var in 
my check_var from 800x592 to 800x600. Console (or whoever) seems to 
attempt to change the mode to its initially desired dimension on many 
occasions.

- This leads to the (unncessary) second mode switch during boot (when 
the "initial console" starts), assumingly because the xres does not 
match fontsize * rows,

- and probably is the reason for that vertical offset I see after this 
mode switch: The text area on the screen is shifted down by exactly 8 
pixels - 600-592=8

Any hints?
