Well My electrical engineering knowledge does not reach as far that I 
would know where to connect what :) I can read a schematic and solder 
based on that, but those pictures from the wiki that I linked, 
http://www.coreboot.org/Developer_Manual/Tools/Dual_Flash  has a small 
PCB, with 2 flash chips on it, but I can't figure out where to connect what.

I do think it's a great idea, and maybe it would be an idea to draw the 
PCB in kicad/geda or the like, and actually have small batches made. I 
know dangerousprototypes.com has loads of small PCB's made for a few 
bux. Having a few on hand of these, and be able to send them to people 
would be great! Stuff one in an envelope and mail it out for the price 
of a stamp.
