I missed this from your earlier email:

Adding support for this screen in Linux is an interesting idea... but
perhaps too much work for too little gain. It can't be GPU accellerated
so DRM doesn't give much value-add here.

Some formats here, namely argb8888 and xrgb8888, have values that are
not derived from DRM, which is why I grouped m1bpp alongside them rather
than at the end of the list. This patch doesn't set a new precedent in
that regard.
