I don't understand why this would be the case: 3. It recently came to my attention that this microcode update might forbid unsupported (by Intel) overclocking on 4th gen Core "K" processors installed on motherboards that lack a Z-series chipset.

They only want people that pay extra for Z chipsets to be able to overclock. Pretty ballsy of them to release an update that disables functionality for no good reason. (Intel's bottom line isn't a good reason.)

Following some of the links in the mail thread[1] it sounds like intel only allows it on the Z series chipsets for various reasons. And some mother board manufacturers have been enabling it on the sly to let people without them to do some amount of overclocking.

  I wonder how does it detect the chipset being used.

    It's in the CPU which is connected to the physical memory. Detecting the chipset is as trivial as reading a few bytes from the memory.

This has mostly always been the case. Also consider the microcode has to be loaded every time the OS is booted (or be baked into the bios image). So it doesn't really mean much.
