Update, after debugging: the failure to find a working video mode had
nothing to do with the 4K monitor, and everything to do with a problem
in our GRUB configuration generator and having /gnu/store on a Btrfs
submodule.
In particular, this generated pice of GRUB configuration:
--8<---------------cut here---------------start------------->8---
if loadfont
/rootfs/gnu/store/m1fx9h7gzw78k0n4da0khbga5i6k8ipk-grub-2.04/share/grub/unicode.pf2;
then
setup_gfxterm
fi
--8<---------------cut here---------------end--------------->8---
was causing the setup_gfxterm to not be called due to failing to resolve
the unicode.pf2 file when using a Btrfs submodule.
The originally attached patches still provide some >
simplification/cleanup that would make it good to merge nontheless, I
believe!
