Apply this patch to your src tree:
http://people.freebsd.org/~ariff/misc/idlecpu_apic_5.diff

And then add the following to /boot/loader.conf:
hw.apic.idle_cpu="2"

Rebuild the kernel and reboot.

The patch above was created by Ariff Abdullah <ariff_at_FreeBSD.org>, you
should read the following PR/followups for a (very) detailed
discussion regarding this Turion 64-X2 problem:
http://www.freebsd.org/cgi/query-pr.cgi?pr=i386/104678

PS: I also own a notebook with this CPU, and this patch solved things
here... both CPU cores are usable and the system is stable.
