Bug description:
  Netplan autopkgtests related to Wireguard are currently failing (see
  below) on Noble ppc64el. Trying it manually on a ppc64el system, I
  can't load the kernel module:

  ~# modprobe wireguard
  modprobe: ERROR: could not insert 'wireguard': No such device

  
  And because of that the interface can't be created:

  Jan 19 15:47:59 mantic-bos01-ppc64el NetworkManager[2414]: <warn>  [1705679279.5797] platform-linux: do-add-link[wg0/wireguard]: failure 95 (Operation not supported - Unknown device type)
