l'explication de Debian:

   Which name: x86-64, x86_64, or AMD64?
   
   This is confusing, because the name has changed over time. The initial
   name for the architecture was x86-64. However, around the time of the
   Opteron launch, AMD stated the name x86-64 ceased to exist and was
   replaced by the name AMD64. AMD acknowledge that the name x86_64 still
   exists and is what is reported by the 64-bit Linux kernel for this
   platform. In a message from AMD's Marc Miller [1], he recommends using
   the name AMD64 in places where i386 or i686 might be used and use x86_64
   in places where x86 may be used.

intéressant d'apprendre que l'architecture AMD64 (ou x86-64) a été
développée comme un standard ouvert, ce qui explique que les Pentium IV
supportent également ce standard. Je l'avais déjà `remarqué' sans
réaliser la raison.
  
PS: installer des binaires non packagés par la distribution,
    pose souvent beaucoup de problèmes. Une idée est de les lancer dans
    une prison chroot(2) ou via un contexte VLS pour minimiser les
    risques.
