I realized that in SB case GRUB2 with linuefi patches does not have
a lot features (correct me if I am wrong). So you are able to just
load Linux or something which supports Linux Boot protocol. It is
not so flexible as it was designed. I think that it should be changed
and support for others systems/hypervisors should be added without
breaking SB support of course. GRUB2 upstream solution is preferred.
