So the answer looks like "maybe". Perhaps someone can suggest a motherboard where this is known to work? I have recently done some things using VIA mini- and nano-itx boards (I've just finished a digital picture frame based on a 500 MHz nano-itx) and they would be ideal for what I have in mind now, but if they are known to not work then I would consider something else. The nano-itx has a 512 Mbyte LPC flash chip; presumably there is no freely-available documentation about how it is connected up. Is there a way to know what will work apart from trying it?
