Well, now I'm stunned.

With APIC and ACPI enabled, my machine isn't even able to boot
completely, it'll most certainly crash before the init scripts are

Now, I modified the init scripts to do "athcool off" as the first
thing at all (I don't have any "CPU disconnect" BIOS setting) and it
not only booted, but I even can't seem to make it crash using my
hdparm/grep/whatever tests...

I don't know if it's "rock solid" yet, but at least the difference is
huge. It really seems like that made the problem go away!
