Well... Yes, they are challenging to boot, because without working
display, debugging them is hard/impossible. Very few people have
serial cables for those, but at least the N9 is pretty common.

PostmarketOS is interested in using it as a target. I'm interested in
keeping it going. With working display, I'm pretty sure I can prevent
regressions... and there could be even some improvements :-).

Best regards,
