With `set debug="chain,secureboot,dl"` added to the Grub menu entry, we get a flash of:

  SecureBoot: 0
  SetupMode: 0
  linuxefi_secure_validate: 1
  No shimlock protocol loader/efi/chainloader: Secure boot is not enabled

Looks like Grub is insisting on Secure Boot, which we need to disable in order to boot Linux.
