Details:

Initially in grub2 the configuration is set to GRUB_GFXMODE=auto. On several
systems grub seems to be unable to autodetect the proper resolution.
(In grub console "videoinfo" returned no (!) output on my system, a thinkpad
x201) After altering to GRUB_GFXMODE=1280x800 which is the known resolution of
my screen, my lovely bootmenu was visible again.

Formerly grub's default configuration seemed to be GRUB_TERMINAL= console,
which now has been commented out. That leads to a nice output (as grub themes
are supported) if it works. If not, it leads into the dark...

As most users are not encountering problems with graphic mode it would be nice
for the few (?) others to provide a console fallback mode, if the autodetect
fails.
