Along with http://en.wikipedia.org/wiki/CPUID and > http://www.sandpile.org/x86/cpuid.htm#level_0000_0001h (IA-64) Don't those semantics contradict the use in qemu-system-x86_64 or qemu-system-i386 rather than qemu-system-ia64 then? We don't model ia64 CPUs here (just like we don't model ppc64 CPUs in ppc) so the flag could never become 1 IIUC.
