Not without loading the xorg graphics stuff... graphics chips from the last
15 or 20 years have lots of chip specific state that only the graphics
stuff knows about... IIRC, it only knows about it because it put the
graphics into a known state... it's the main reason laptops stopped
suspending in the early 2000s... it looks to be a lot of work for a
relatively rare use case...
