Subject: [PATCH v3] Add hidden menu entries
The menu infrastructure is quite powerful. It allows you to define menu
entries that can contain arbitrary grub commands that can do a lot more
than just boot kernel entries.
For some of these it makes sense to hide them inside the normal menu
though and instead have them available through hotkeys that get advertised
differently. My main use case is to switch to the serial console when
gfxterm is loaded.
So this patch adds support for hidden menu entries that are accessible
using hotkeys, but are not accessible in the grub menu.

Subject: [PATCH] SUSE: Add the "t" hotkey
While graphical output is fancy and nice, in some environments (EFI) we can
only have fancy graphical on frame buffer _or_ ugly serial on any output.
To give the user a nicely graphical screen in the default case, but still
allow them to get their boot menu on the serial console, let's add a new
hidden option "t" that switches the output device back to the firmware default.
