That would be me.  Here's a summary of what I encountered (all this can 
be found in the "SMP problems with -CURRENT (and BETA5)":

With HTT enabled in the BIOS:

1) With ACPI and APIC enabled: Locking up after detecting my hard drives 
and launching the second processor.

2) With ACPI disabled and APIC enabled:  Crashing with a "Fatal trap 9".

3) With both ACPI and APIC disabled: Success.

With HTT disabled in the BIOS:

1) With ACPI and APIC enabled:  Locking up after detecting my hard drives.

And, I'd agree with your assesment that, no matter the cause, this is a 
pretty significant show-stopping bug :-)
