jfwiw, I do actually have Shell.efi very nearly loading in sandbox.. it crashes part-way through startup (shortly after reading "ShellOpt" variable) and I haven't had a chance to debug further.. but I suspect in some form or another having VA != "PA" in sandbox is biting us. Anyways, getting a bit off topic, but separate .efi in sandbox doesn't seem like it should be completely out of the question for sandbox.. and it would make sandbox *way* more useful for EFI testing, since this is really half of the point of efi..
