The comment suggests that this only applies if a kernel parameter
forces a 1080p mode, but this isn't true for all displays.  Mini v2 on
a 4K TV caused a mode switch every time fbwhiptail started or exited -
the kernel selects 3840x2160 for the console, but a 1080p mode is
present and fbwhiptail selects it.  This mode switch can take a long
time and may be unreliable (my Samsung TV often fails to sync to the
new mode).

Graphical scaling in fbwhiptail preserves the menu size so the menus
aren't tiny.  Setting the Linux console font ensures the console is not
tiny.
