A few other points you may wish to consider are:

The 6 month lifespan (approximately) of an off-the-shelf. I'm not
against LinuxBIOS (I've been lurking on the list since 1999) but the
motherboard you pick today may be out of production by the time you go
to market.

Will your company allocate resources in the future to keep up with
LinuxBIOS ports for new boards or revs? It will be great if you do.
Hopefully MSI will also get onboard with LinuxBIOS and support this from
the factory.

Your issues with thermal management are a bit off topic on this list,
but a 100% passively cooled AM2 designs are possible. We have done them.
I've never seen an off-the-shelf mainboard come with an entirely passive
cooling system for any cpu over a few (5-10) watts. You would however be
able to develop a passive cooling system for the K9N that use the <35 W
AM2 processors. I just don't see this coming out of the box.
