Just for the record, for an older Phenom with dmesg:

CPU: AMD Phenom(tm) II X6 1090T Processor (3214.31-MHz K8-class CPU)

#x86info -a | grep "CPU Model"
CPU Model (x86info's best guess): Phenom/Athlon/Sempron/Turion
(II)/Opteron (PH-E0)

#x86info -a | grep Microcode
Microcode patch level: 0x10000bf

#/usr/local/etc/rc.d/microcode_update onestart
Updating CPU Microcode...
Done.

#x86info -a | grep Microcode
Microcode patch level: 0x10000bf

#grep microcode_update /var/log/messages
---

So no recent update and no log messages, as expected ;)
