I think we are not understanding eachother....
The save/restore thing is a different matter than the var thing
altogether....
The var for each vc is simply having a different mode for each VC
and not relying on the doggy magic mode setting done by fbcon to
set a mode matching the VC size. fbcon is responsible for setting
the proper mode for each VC upon entry to that VC, and so with the
above, that mean just having a var per VC.
