Both are kernels of SLES11 xon x86_64.

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.
