Tak se do toho dáme.
Začal jsem znovu a /etc/grub.d/00_header jsem upravil takto (dle zmiňovaného návodu):

V podstatě šlo o přidání řádky set gfxpayload=keep.
Pak jsem přidal požadované rozlišení do /etc/default/grub
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.

Zkoušel jsem i jiné a i ve formátu 0x0367, ale výsledek je pořád stejný. Při bootu se mi totiž zobrazí hláška
error: unknown command 'terminal'a pak se pokračuje v malém a ošklivém rozlišení.
Koukal jsem, že jednomu člověku ze jmenovaného threadu to dělalo také, ale na jeho postupu nevidím vůbec žádnou odlišnost od hlavního navrhovaného postupu, takže nevím, co bych měl udělat jinak.
Ještě přiložím cat /proc/cmdline:

Už si vážně nevím rady a přitom to vypadalo na velmi jednoduchou opravu. Díky za případné rady.
