From what I can see from these docs, Intel's "IA-32e" is very very close
to the natural combination of P4 with AMD64. No hyperlink stuff, but
otherwise the same. The local APIC and performance counters should be
exactly as in P4 :-)

What about naming? IA-64 is taken, AMD64 is too specific, Intel's
"IA-32e" sounds too vague, and I find x86-64 / x86_64 difficult to type.
"x64" perhaps?
