Did you read my original mail ? :)
With this patch, I force a set_par, which resets the mode and the engine
on a switch from a KD_GRAPHICS VT to a KD_TEXT VT. I don't do anything
at this point when the current console is switched from KD_GFX to KD_TEXT
without involving a VT swith as, afaik, there's no fbcon hook for that
at this point. (A hack would be possible, but I want to avoid it).
Ben.
