So we might check for it. Good!

And suddenly certain i486 systems do not work anymore? Well, I haven't
actually heard of an i486 SMP system running Linux so far (maybe they just
work fine, so no reports). But we could try the following, instead:
if (boot_cpu_id != -1U
&& APIC_INTEGRATED(apic_version[boot_cpu_id]) && !has_apic)
/* No SMP */
It should filter broken MP-tables and work fine on all 82489DX-based
systems. I'll have a patch soon if we agree on this solution.
