Overall, this feature is a great help for developers working in the
framebuffer or console layer.  There is not need to continually reboot the
kernel for every small change. It is also useful for regular users who wants
to choose between a graphical console or a text console without having to
reboot.

Instead of the sysfs attribute, what about creating a new escape
sequence that you send to the console system to detach? Doing it that
way would make more sense from a stacking order. It just seems
backwards to me that you ask a lower layer to detach from the layer
above it. The escape sequence would also work for any console
implementation, not just fbcon.

If console detached this way and there was nothing to fallback to
(systems without VGAcon), it would know not to try and print anything
until something reattaches to it.
