Details:

`set gfxmode=auto` does not necessarily (if not never) make `terminal_output
gfxterm` switch to the preferred mode found in the EDID.

It would be nice to have a switch in videoinfo that makes it print nothing but
set gfxmode to the preferred mode, so we can have a "portable" grub.cfg that
sets gfxmode dynamically on different machine.
