Is that information really more important than the ability to boot? Correct me if I'm wrong, but linux was able to boot without the boottime QueryVariableInfo() call up until 3.9-rc7, and it still does on systems that do not use EFI stubs (ie grub and elilo). It is only when linux uses EFI stubs (ie grub2) that linux makes the boottime QueryVariableInfo() call. So why is that call, or whatever is dependent on it, more important than booting?
