CPU: AMD Athlon(tm) Processor (1194.43-MHz 686-class CPU)
 Origin = "AuthenticAMD"  Id = 0x661  Stepping = 1
 AMD Features=0xc0440000<<b18>,AMIE,DSP,3DNow!>

Note the FXSR (fast context save and restore) and the SSE flag are there.

This is an AthlonMP system:
FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
 cpu0 (BSP): apic id:  1, version: 0x00040010, at 0xfee00000
 cpu1 (AP):  apic id:  0, version: 0x00040010, at 0xfee00000
 io0 (APIC): apic id:  2, version: 0x00170011, at 0xfec00000

and it works very nicely. :-)
