Not sure in general, but I have an X2 which says the following
in /var/run/dmesg.boot:

FreeBSD 6.1-PRERELEASE #1: Sat Feb 11 17:12:37 EST 2006

I'm running with /boot/loader.conf containing:
kern.smp.disabled="1"

because that's the only way that the 4front-tech OSS sound card
driver for my m-audio delta 1010 will load. (If I have both CPUs
going then it is unable to allocate a contiguous chunk of 30k-ish
RAM, 64k-aligned, by the time it gets going, in /etc/rc.local.)
Dunno if that sysctl would change the way the CPU is reported,
though.

I'm happy to help answer any questions, because there's a few
other pieces of my shiny new GA-K8N9 motherboard that don't work
properly too.  (nve0 times out a lot and the system freezes up
for a second or two whenever it does.  I'm hoping that recent
comments about interrupt routing fixes will mean that this'll
get better soon.)

GA-K8N9 is an nForce 4 based board.  I only have 1G of RAM at
the moment, so I'm not seeing this problem.

Cheers,
