Which uses an DRM_FORMAT_XRGB8888 intermediate, and
drm_fb_xrgb8888_to_gray8() and repaper_gray8_to_mono_reversed()
to convert from truecolor to monochrome.  I guess that would work,
as this is a slow e-ink display.  Have fun as a text console ;-)

But that's really just a question of optimization. The console is 
userspace-ish in that no one has asked for monochrome support yet. So 
it's not there. We could add it if it's ever needed.
