One thing to note is that in the dmesg you posted, there's no "ioapic"
probed. That suggests it's not really finding the APIC, which would
be why SMP is failing. It'd be getting that from ACPI normally, but
AIUI (I'm way out of my depth here) it could find them in other ways.
I vaguely recall somebody (John Baldwin, maybe?) doing something in
this area of ways of enumerating CPU's/APIC's in the last 6
