Hm, and in your dmesg I see that you have the situation that I described: your
CPU is supposedly dual-core (and supports HTT on top of that), but FreeBSD for
some reason [*] sees only one cpu, e.g.:
> cpu0: <ACPI CPU> on acpi0

So I am quite sure that the patch that I posted should help you.

[*] - yes, I do want to see your *verbose* dmesg from the working kernel.
