Thanks, with the above patch my system is now working properly, and I'm
(finally) able to use both CPU cores.
CPU: AMD Turion(tm) 64 X2 Mobile Technology TL-50 (1607.33-MHz K8-class CPU)
Origin = "AuthenticAMD" Id = 0x40f82 Stepping = 2
Cores per package: 2
FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
cpu0 (BSP): APIC ID: 0
cpu1 (AP): APIC ID: 1
cpu0: <ACPI CPU> on acpi0
cpu1: <ACPI CPU> on acpi0
