Allow the saving and restoration of VGA text mode. The state is saved on the first open and restored on the last close. Because of the non-linear mapping of the VGA registers to the MMIO space, this will be done only on X86 platforms where the device is the primary display. An echo 0 > /sys/class/vtconsole/vtcon1/bind will convert the display from graphics to text mode.
