I was also well impressed with this:
Processor family (386, 486/Cx486, 586/K5/5x86/6x86, Pentium/TSC, PPro/6x86MX, K6/II/III, Athlon) [PPro/6x86MX] defined CONFIG_M686
/proc/driver/microcode - Intel P6 CPU microcode support (CONFIG_MICROCODE) [N/y/m/?] (NEW) ?
If you say Y here you will be able to update microcode on
Intel processors in P6 family, e.g. Pentium Pro, Pentium II,
Pentium III, Xeon etc. You will obviously need the actual microcode
binary data itself which is not shipped with the Linux kernel.
Contact Intel to obtain the latest revision of microcode for
your CPU(s). With this support compiled you can use dd(1) to write
microcode, for example:
# dd if=/etc/microcode of=/proc/driver/microcode bs=98304 count=1
You need to be superuser to do that.
This driver is also available as a module ( = code which can be
inserted in and removed from the running kernel whenever you want).
The module will be called microcode.o. If you want to compile it as a
module, say M here and read Documentation/modules.txt.
Mad. Stone mad.
