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.
Yeah, I have a handful of i686 hardware newer than 2001 that runs pretty well.
