Most likely, no. Didn't particularly check the list, but I don't think
it contains any AsRock boards right now.

If someone with the hardware steps up to do a port there is a chance
indeed. 

That someone could be you! :-)

Basically the way this works is that you look for the most similar board
in the tree, start out with that, and change it until everything works
the way you want it to. This might be an effort anywhere from an hour to
12 months ;) Most likely with AMD chipsets it's rather less time since
AMD supports coreboot quite well.

Also be sure that you have any means of recovery. A second flash chip if
yours is socketed, or an external eeprom burner for instance.

Have not looked into it, but I believe I read that the 3core/4core switch
is done by some code running on the EC, so it might not be a lot of work
on the bios side.
