x448 keys are created as version 5 keys and version 5 keys come with a
32 byte fingerprint (v4 has 20 bytes). Also the way the keyid is
computed has changed: For v5 keys the keyid are the left most 32 or 64
bits.
For display purposes an abbreviated hex format is used. It might be
that the keyid is then display wrongly - frankly I have not checked
because keyids are rarely used. Even the formatted fingerprint ("gpg
--fingerprint") is not very useful anymore because the majority of users
just copy+paste the fingerprint and thus the straight hex format as
displayed by "gpg -k" is more useful. Here is an example:

where a v5 subkey has been added. Note also that I use the
--with-subkey-fongerprint option which will eventually be the default.
