Yeah I think so, if you didn't find the last bootinfo entry within some reasonable bounds everything is probably broken and you shouldn't continue. I think for most real machines (Amiga etc) there aren't many entries but for the virt machine maybe there is an entry per virtio mmio device so there might actually be a lot of them there.
