[PATCH] fbcon: Add ability to save/restore graphics state
Add hooks to save and restore the graphics state. These hooks are called in fbcon_blank() when entering/leaving KD_GRAPHICS mode. This is needed by savagefb at least so it can cooperate with savage_dri and by cyblafb. State save/restoration can be full or partial.
