Yep,

those are all before 3.2.

Well, if you still want to find out the microcode revision on those
boxes, on both AMD and Intel you can do as root:

$ rdmsr 0x8b

You need the msr.ko kernel module loaded or built-in (CONFIG_X86_MSR
option enabled) for this and rdmsr is from the msr-tools package.

HTH.
