Ho trovato la soluzione direttamente sul sito
www.debian-multimedia.org: andava aggiunta l'opzione --root=/
Il comando e le opzioni lanciate sono questi:
debmirror debian_multimedia/ --host=www.debian-multimedia.org --section=main --arch=i386 --progress --verbose --nosource --method=http --dist=etch --ignore-small-errors --root=/ --ignore-release-gpg
Sottolineo che senza l'opzione
--ignore-release-gpg il comando si bloccava con questo errore:
Get Release files.
[0%] Getting: dists/etch/Release... ok
[0%] Getting: dists/etch/Release.gpg... ok
gpg: Signature made mer 20 feb 2008 20:01:48 CET using DSA key ID 1F41B907
gpg: Can't check signature: public key not found
Release signature does not verify.
Errors:

Failed to download some Release or Release.gpg files!

La spiegazione si trova sulla stessa pagine di debian-multimedia.org
The Release.gpg check has been rewritten to use gpgv, the same
method as used by apt and debian-installer. As a side effect the
keyring file has been changed to ~/.gnupg/trustedkeys.gpg.
Existing setups must copy their pubring.gpg to trustedkeys.gpg or
import the relevant keys there. This allows to only have the
Archive keys in trustedkeys.gpg while still having a pubring.gpg
for other use.
Per finire aggiungo che i binari i386 pesano in tutto 191Mb.
