my dmesg output contains
FreeBSD 6.0-STABLE #4: Sun Nov 20 19:54:13 CET 2005
ACPI APIC Table: <Nvidia AWRDACPI>
Timecounter "i8254" frequency 1193182 Hz quality 0
CPU: AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ (2211.34-MHz
Origin = "AuthenticAMD" Id = 0x20fb1 Stepping = 1
real memory = 1073676288 (1023 MB)
avail memory = 1026330624 (978 MB)
FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
cpu0 (BSP): APIC ID: 0
cpu1 (AP): APIC ID: 1
so it looks like FreeBSD 6 stable (and above) supports them.
Btw: why are you trying to use FreeBSD i386 for an AMD64 cpu ?
