OK, so I am completely confused about microcode. Based on the wiki article you can use any microcode that has the same numbers in any order. This is not explained in the wiki article so I do not know what to put into my kernel shy of trying every single one until I find the one (ones?) which work. The wiki shows "306c3" in the example, but chooses "06-3c-03" as shown here. How do you convert from one number to the other? This was a billion times simpler with the old package that handled this stuff for you.

For example, I am bombarded with a TON of options instead of only one.
Code:

tangent ~ # iucode_tool -S -l /lib/firmware/intel-ucode/*
iucode_tool: system has processor(s) with signature 0x000006fd

So none of that matches but it shows a ton of selected microcodes, but none of them look like what the wiki selected to go into the kernel! Do I put all of those into the kernel? Help!

Just for info why not
Code:
029/001: sig 0x000006fb, pf_mask 0x80, 2010-10-03, rev 0x00ba, size 4096

seems the max rev number?

Well, bundle 029/001 doesn't match the CPU signature
Code:
tangent ~ # iucode_tool -S -l /lib/firmware/intel-ucode/*
iucode_tool: system has processor(s) with signature 0x000006fd

The only microcode bundle with matching signature is 030.
Jaglover got it right:

See that's what confused me. It showed an entire list of selected microcodes and that threw me off.
