We haven't heard from anyone using boards with this hardware in SMP.

I don't know how many amd64 users are trying for SMP, but it's interesting
that no one seems to be doing it successfully with Adaptec controllers
(possibly qualified to "on motherboards with this chipset").

Yup.  But I oughta try the experiment of disabling EVERY ACPI feature that
I can.

I'm also gonna boot NetBSD again and see whether I spot anything interesting.
What's bugging me is that, despite people having told me you can't have SMP
without ACPI, I thought I did the NetBSD test back when I had ACPI disabled
in the BIOS.  I'm probably just remembering wrong, but now I have to go look.
