There was some guide somewhere on how to download the stock ROM.

The presence of CPU microcode should be the least of your concerns. Really. 
How about an out-of-band processor with full DMA access, and networking access 
transparent to the OS?
Seriously, the CPU microcode is nothing. Besides, nobody cares if an internal 
PLL is configured properly so that the CPU can switch to its highest clock 
without hanging.

AMD is your best bet, but be prepared to get your feet wet. Server boards are 
hard to find, and you'll most likely need to port it.

Chromebook, if you actually want to vote on free firmware. If you want to stick 
it to Intel (which I think you should), there are ARM models available. I also 
hear rumours of an octa-core coming soon. There are also some well-supported 
Lenovos, but getting one counts as not voting.

Sounds like a foul's paradise. Their firmware most likely installs some 
microcode updates.

Ask away, but please keep Stallmanism out of it. CPU microcode is better 
compared to a hardware descriptor than a set of instructions, and it's 
probably a mix of both. It's definitely not software in the normal sense of the
