It will probably work, but it's more of a happy accident than a
deliberate decision. I would still suggest it if it were incompatible
with Pentium 4 CPUs without x86-64 support. (The fewer of these
Netburst power guzzlers are running, the better, to be honest.)
Certainly, I'm no netburst fan either. But the last[*] 32-bit-only
Intel chip was Yonah (Core 1), which went out of production in 2008-
ish, so there's about seven years worth of CPUs between the
introductions of SSE2 and AMD64. So this isn't eliminating the
possibility of extant i686 kernels, which "will need an x86-64-capable
CPU" might otherwise imply.
