I tried the newreloc branch
https://code.launchpad.net/~skodabenz/grub/grub2-branch-newreloc but I
found no difference in fuctionality between experimental and newreloc
in case of x86_64-efi (I do not know about i386-efi). "newreloc"
solves the problem of initramfs not being loaded properly and leading
to kernel panic that currently occurs with mainline, but the graphics
problem in experimental also occurs with newreloc, I think this
problem is due to efigfx branch. Is there any command which makes
grub2 stop trying to load a graphics/video mode and instead fallback
to efi simple text protocol? Please include the way mainline handles
the issue, as a fallback option in efigfx, in case no graphics/video
mode is found.

Regards.
