I'm not trying to FUD.

It wasn't clear to me at the time whether the discussion was
geared toward having both APIC and xAPIC support, or only xAPIC

Maybe you could clear that up.

I'm not happy with my Circa 1996 dual P90 box.  It's not
inconceivable that non-xAPIC processors might get deprecated
in the rush to more than 16 CPU's, like my ASUS dual P90
box seems to have been.

Also, the recent change to make SSE instructions the build
default also bit me on one of my machines without SSE support.
